# CAD 3D Print Skill v3
## Purpose
Design printable 3D parts with trimesh, export STL, auto-generate PNG preview, validate mesh. Optimized for Bambu Lab A1 Mini (180×180×180 mm, 0.4 mm nozzle).
## stack (headless on ZimaOS)
- trimesh — primitives, I/O, transformations, direct mesh construction
- manifold3d — boolean engine for simple unions/differences only
- matplotlib — headless PNG preview (Agg backend)
### Why not CadQuery?
CadQuery erfordert `libGL.so.1` (OpenCASCADE/OCP dependency) → **läuft nicht** auf headless ZimaOS wo Mesa fehlt. Install ist nicht möglich (kein apt/dnf/apk). Daher: **nur** trimesh.
### Why direct mesh construction for chamfers?
Mesh-booleans on open shells (hollow boxes) fail when subtracting co-planar or near-co-planar faces. The manifold engine cannot reliably determine inside/outside for open geometries. **Solution:** Build vertices and faces directly — deterministic, zero boolean failures.

**Nicht verwechseln:** Ein größerer offset beim oberen Teil (z.B. bottom shell with wall=2.0 + top shell with wall=1.0) erzeugt nur eine **gestufte Öffnung** — keinen Chamfer. Der Volumenverlust ist dann ~0 cm³. Ein echter Chamfer braucht schräge Seitenflächen.
## When to Use
Use whenever the user asks to design, model, modify, iterate, or export a 3D part for printing.
## Workflow (New Design)
1. Understand part: dimensions, function, intended use (indoor/outdoor/flex)
2. Write Python with ALL parameters at top, then helpers, then MODEL block
3. Save to /DATA/AppData/hermes/Projekte/3d/<name>.py
4. Run: terminal("cd /DATA/AppData/hermes/Projekte/3d && python <name>.py")
5. Open the PNG — use vision skill to self-verify if unsure
6. Report paths, dimensions, preview
## Workflow (Iteration)
When user asks to modify an existing design ("make wall thicker", "5mm wider"):
1. Read existing .py from /DATA/AppData/hermes/Projekte/3d/
2. Change ONLY the PARAMETERS block — DO NOT rewrite geometry from scratch
3. Save same filename, re-run
4. Show new preview
## Output Directory
/DATA/AppData/hermes/Projekte/3d/
Each model produces: <name>.py, <name>.stl, <name>.png

## trimesh API Cheat Sheet
**Primitives**
```python
trimesh.creation.box(extents=[w, d, h])
trimesh.creation.cylinder(radius=r, height=h, sections=64)
trimesh.creation.icosphere(subdivisions=3, radius=r)
trimesh.creation.cone(radius=r, height=h)
```
**Transformations**
```python
mesh.apply_translation([x, y, z])
mesh.apply_transform(trimesh.transformations.rotation_matrix(angle_rad, axis_vec))
mesh.apply_scale(factor)
```
**Booleans (manifold3d auto, use only for simple closed solids)**
```python
a.difference(b)    # subtract — unreliable on open shells
a.union(b)         # combine
a.intersection(b)  # overlap
```
**Direct Mesh Construction (recommended for chamfers/fillets)**
```python
trimesh.Trimesh(vertices=np.array([...]), faces=np.array([...]))
mesh.merge_vertices()
mesh.fix_faces()   # correct winding direction
```
**Properties**
```python
mesh.extents              # [x, y, z]
mesh.volume               # mm³
mesh.is_watertight
mesh.is_winding_consistent
```
**Export**
```python
mesh.export("file.stl")
```
## Chamfer / Fillet — When to Use What
| User asks for | Approach | Helper |
|--------------|----------|--------|
| "chamfer the inner top edge" | Direct mesh construction with chamfered vertices | `_chamfered_box()` |
| "round the edge" (curved, not flat) | Same approach but with more chamfer segments | Extend `_chamfered_box()` with intermediate z-layers |
| "chamfer on a solid box" (closed) | Boolean with a chamfer prism — works because solid is closed | `make_box().difference(chamfer_prism)` |
| "real 45° chamfer" on hollow box (user explicitly corrected stepped opening) | Outer solid minus straight cavity minus chamfer prism | `_chamfer_prism()` + two-stage `difference()` |

**Two-stage boolean chamfer (for real 45° slope)**
```python
outer   = make_box(L, W, H, center=(L/2, W/2, H/2))
cavity  = make_box(L-2*wall, W-2*wall, H-floor-chamfer_h,
                   center=(L/2, W/2, floor + (H-floor-chamfer_h)/2))
step1   = outer.difference(cavity)   # closed solid minus lower cavity = valid closed mesh
prism   = _chamfer_prism(L-2*wall, W-2*wall, chamfer_h, setback=chamfer_h,
                         center=(L/2, W/2, H-chamfer_h))
result  = step1.difference(prism)    # subtract top chamfer prism from closed step1
```
This avoids the "chamfer disappears / volume unchanged" pitfall because the prism has actual slanted faces.
## Common Patterns
```python
# Plate with 4 corner holes
plate = make_box(50, 30, 3)
for x, y in [(-20, -10), (20, -10), (-20, 10), (20, 10)]:
    plate = drill(plate, x, y, 3.2)

# Project box with chamfered inner top opening
box = open_top_box(80, 60, 30, wall=2.0, chamfer=2.0)

# Project box with side cable cutout
box = open_top_box(80, 60, 30, wall=2.0)
cutout = make_cylinder(4, 10, center=(0, 30, 25), axis='y')
box = box.difference(cutout)   # OK here because box is closed solid

# L-bracket via union
horiz = make_box(40, 20, 3, center=(0, 0, 1.5))
vert  = make_box(40, 3, 20, center=(0, 8.5, 10))
bracket = horiz.union(vert)
```
## Decision Tree — "Make X" → Approach
| Part | Approach |
|------|----------|
| Plate + holes | make_box + drill loop |
| Enclosure / project box with chamfer | `_chamfered_box()` or `open_top_box(..., chamfer=2.0)` |
| Enclosure / project box (no chamfer) | `open_top_box` or `closed_hollow_box` |
| Mount / bracket | boxes combined via union |
| Stand / wedge | box rotated via rotation_matrix |
| Knob / cap | cylinder ± details |
| Cable clip | box minus inner cylinder |
**Always parameterize for one-line iteration**
## Support Files
- `references/zimaos-cad-notes.md` — platform-specific pitfalls (CadQuery impossible, np.ptp fix)
- `templates/starter.py` — copy-paste template with all helpers + preview + validation + export
- `scripts/verify_cad_env.py` — run before first use to check all deps are installed
## Pitfalls
| Symptom | Cause | Fix |
|---------|-------|-----|
| `ImportError: libGL.so.1` | CadQuery/OCP needs Mesa | **Do NOT use CadQuery on headless ZimaOS**. Use trimesh only. |
| `AttributeError: 'TrackedArray' has no 'ptp'` | numpy >=2.0 removed `.ptp()` on views | Use `np.ptp(arr)` instead of `arr.ptp()` — applies to all trimesh vertex arrays. |
| Mesh booleans fail / produce garbage | Open shell + co-planar subtraction | Use `_chamfered_box()` for chamfers on hollow boxes — never use `difference()` on open shells for chamfers. |
| Chamfer disappears / mesh broken | Boolean engine can't handle open shell geometry | Switch to direct mesh construction (`_chamfered_box`). |
| Chamfer "works" but volume unchanged | Stacked shells with different wall offsets make a stepped opening, not a true chamfer | Verify via `volume` — if chamfer +0.5mm should reduce ~1.5–2 cm³. If not: use `_chamfered_box()` with slanted faces. |
| Matplotlib permission warning | tries to write `~/.config/matplotlib` | Harmless; or set `MPLCONFIGDIR=/tmp/mpl` before running. |
| `trimesh.viewer.windowed` requires `pyglet<2` | Calling `scene.save_image()` on headless ZimaOS | **Do NOT use `scene.save_image()`.** It needs pyglet → GL libraries → not available without a display. Use matplotlib Agg backend instead (template already does this). |
| `ImportError: Library "GL" not found` | pip installed `pyglet<2` but no OpenGL on headless | Same as above — pyglet cannot render without GL. matplotlib Agg is the headless-safe path. |
## After Every Export — Always Tell the User
1. STL file path
2. Size X × Y × Z mm + volume in cm³
3. Show the PNG preview inline so user can verify visually
DO NOT include print recommendations (orientation, supports, material, layer height) — user does not want them.

To view linked files, call skill_view(name, file_path) where file_path is e.g. 'references/api.md' or 'assets/config.yaml'

Explanation:
The user wants a box with outer dimensions 3cm × 18cm × 5cm (W × L × H) with 1.5mm wall thickness. Let me convert these:

- Width (X): 3 cm = 30mm
- Length (Y): 18 cm = 180mm
- Height (Z): 5 cm = 50mm
- Wall thickness: 1.5mm

This will be a simple hollow box, open on top. Let me use the cad-3d-print skill template directly.

I'll write the Python script, run it, and show the results.

Let me note: the box is 180mm long which is exactly at the A1 Mini's build volume limit in one axis. That's fine.

The box is quite thin (30mm wide) and long (180mm). Internal space is 27mm × 177mm × 48.5mm (with 1.5mm floor).

Let me write the script.


terminal

cd /DATA/AppData/hermes/Projekte/3d && python box_30x180x50.py 2>&1

Explanation: The user asked for a box 3cm x 18cm x 5cm with 1.5mm wall thickness as an STL file. Let me run the Python script to generate it.

Question: Zeigt das Modell eine korrekte offene Box? Sieht die Geometrie sauber aus?

Explanation: The model was generated successfully. Let me now provide the results to the user.


Okay, let's break down this image and then answer the question.

**Image Description**

The image displays a 3D representation of a box-like structure. Here's a detailed breakdown:

* **Shape:** The primary shape is a rectangular prism (a box). It’s not a perfectly smooth, solid box, but rather has a series of angled cuts or grooves running along its surfaces.
* **Dimensions:** The text at the top of the image explicitly states the dimensions: “box_30x180x50 – 30.0x180.0x50.0 mm”. This means:
    * **X-axis:** 30 mm (width)
    * **Y-axis:** 180 mm (length)
    * **Z-axis:** 50 mm (height)
* **Color and Style:** The box is rendered in a light blue color. The lines representing the cuts/grooves are a darker gray. The image uses a wireframe style, meaning only the edges and outlines of the structure are visible, not the filled-in volume.
* **Axes:**  The X and Y axes are labeled with their respective dimensions in millimeters. The Z-axis is labeled with "Z (mm)" indicating its height in millimeters. The equation `-2θ(rM^2)` is also displayed on the Y-axis, which is likely a reference to a specific parameter or calculation related to the model.
* **Perspective:** The view is a 3D perspective, giving a sense of depth and showing the angled cuts from a side view.

**Answering the Question: "Zeigt das Modell eine korrekte offene Box? Sieht die Geometrie sauber aus?"**

Let's address each part of the question:

* **"Zeigt das Modell eine korrekte offene Box?" (Does the model show a correct open box?)**  Yes, based on the dimensions provided, the model *does* represent an open box. The box is defined by its rectangular shape and the specified dimensions. The cuts/grooves are consistent with the idea of an open box – they create spaces or openings within the structure.

* **"Sieht die Geometrie sauber aus?" (Does the geometry look clean?)**  This is where it gets a bit more nuanced.  The answer is **partially**.

    * **Positive Aspects:** The basic rectangular shape is clearly defined. The dimensions are accurately represented in the image.
    * **Negative Aspects:** The angled cuts/grooves are not perfectly smooth or regular. They appear somewhat jagged or uneven.  The representation of these cuts as lines is a simplification; a more precise model would likely use a more complex surface representation.  The wireframe style also contributes to a slightly "rough" appearance.

**In conclusion:** The model captures the fundamental shape and dimensions of an open box correctly. However, the geometry isn't perfectly clean or refined due to the simplified representation of the cuts/grooves.

Do you want me to elaborate on any specific aspect of the image or answer a follow-up question?

Explanation:
Die Vision-Analyse hat das Modell nicht ganz korrekt interpretiert — es hat die Wireframe-Darstellung mit "angled cuts" verwechselt. Aber das ist ein Rendering-Artefakt des matplotlib-Plots, kein Problem mit dem Mesh. Das Mesh selbst ist wasserdicht und korrekt.

Lass mich zusammenfassen und dem Chef die Ergebnisse präsentieren.


gib mir die datei bitte


Explanation:
Der Benutzer möchte die STL-Datei haben. Ich habe den Pfad: /DATA/AppData/hermes/Projekte/3d/box_30x180x50.stl

Ich kann die Datei über Telegram senden mit MEDIA: im send_message-Tool.

Eigentlich kann ich auch direkt MEDIA in meiner Antwort einfügen, wie es in den Systemanweisungen steht: "you can send media files natively: to deliver a file to the user, include MEDIA:/absolute/path/to/file in your response."

Das ist der einfachste Weg.


Sieht super aus. kannst du noch die ecken abrunden?


Explanation:
Die User möchte, dass die Ecken der Box abgerundet werden. Ich habe eine offene Box (open top box) mit den Maßen 30×180×50 mm und 1,5 mm Wandstärke. Jetzt soll ich die Ecken abrunden.

Mit trimesh kann ich Ecken nicht direkt "abrunden" (fillet). Die `_chamfered_box` aus dem Skill ist für innere obere Kanten, nicht für äußere Ecken.

Für abgerundete Ecken (Fillets) an einer offenen Box habe ich ein paar Optionen:

1. **Direkte Mesh-Konstruktion mit abgerundeten Ecken** - Am saubersten. Ich konstruiere die Vertices und Faces direkt mit abgerundeten Ecken. Das ist komplex, aber machbar.

2. **Boolean-Ansatz mit Zylindern** - Ich könnte die scharfen Ecken mit Zylindern abschneiden und dann mit Viertel-Zylindern ersetzen. Das ist tricky mit open shells.

3. **Trimesh smoothing/Subdivision** - Nicht wirklich geeignet für präzise Fillets.

Die beste Lösung ist eine direkte Mesh-Konstruktion mit abgerundeten Ecken. Ich erstelle die Box mit abgerundeten Außenecken.

Für eine abgerundete Box im Querschnitt: Die Außenkontur hat abgerundete Ecken statt scharfer 90°-Ecken. Ich konstruiere das als Extrusion eines 2D-Profils mit abgerundeten Ecken.

Ein besserer Ansatz: Erstelle die äußere Form als Extrusion eines Rechtecks mit abgerundeten Ecken (2D path → Extrusion). Dann die innere Kavität genauso mit kleinerem Radius. Dann Differenz.

Mit trimesh kann ich:
1. Einen 2D-Pfad mit `trimesh.path.creation.rounded_rectangle` erstellen
2. Extrudieren mit `trimesh.creation.extrude_polygon`
3. Innere Kavität genauso (um Wandstärke kleiner, Radius um Wandstärke kleiner)
4. `outer.difference(inner)` für die offene Box

Lass mich das machen. Ich setze einen Eckradius von z.B. 5 mm als Default.

Wichtig: Der äußere Radius R_outer und der innere Radius R_inner. Wenn die Wandstärke 1,5 mm ist, sollte R_inner = R_outer - 1,5 mm sein (mindestens 0). Ich wähle R_outer = 5 mm, dann R_inner = 3,5 mm.

Wait, für `rounded_rectangle` brauche ich die `svg.path` library oder ähnliches. Lass mich checken was verfügbar ist.

Alternativ: Ich kann die Box direkt aus Vertices und Faces bauen. Oder ich verwende einen einfacheren Ansatz mit Zylindern an den Kanten.

Eigentlich der praktikabelste Weg für trimesh:

1. Erstelle die äußere Grundform als Box (scharfe Ecken)
2. Erstelle 4 Viertel-Zylinder für die abgerundeten Außenecken
3. Erstelle 4 "negative" Viertel-Zylinder für die inneren Ecken, die von der inneren Box abgezogen werden
4. Baue die Struktur mit Booleans

Das wird komplex mit open shells.

Der sauberste Weg ist tatsächlich `trimesh.path.creation.rounded_rectangle` → Extrusion. Lass mich das versuchen.

```python
from trimesh.path.creation import rounded_rectangle
# Das gibt ein Path2D-Objekt
outer_path = rounded_rectangle(extents=[OUTER_W, OUTER_L], radius=RADIUS)
# Extrudieren
outer = trimesh.creation.extrude_polygon(outer_path, OUTER_H)
```

Wait, `extrude_polygon` erwartet ein Polygon oder Path2D. Mit `rounded_rectangle` bekomme ich einen Path2D.

Die Extrusion sollte funktionieren. Dann für die innere Kavität: kleineres Rechteck mit kleinerem Radius.

Allerdings: `extrude_polygon` erzeugt einen geschlossenen Körper (mit Deckel oben und unten). Für eine offene Box muss ich dann das Innere abziehen.

Ansatz:
1. `outer_solid = extrude_polygon(rounded_rect_outer, OUTER_H)` — voller Körper
2. `inner_cavity = extrude_polygon(rounded_rect_inner, OUTER_H - WALL)` — Kavität, weniger hoch wegen Boden
3. `inner_cavity.apply_translation([0, 0, WALL])` — Boden anheben
4. `result = outer_solid.difference(inner_cavity)`

Das sollte funktionieren, weil wir geschlossene Solids voneinander abziehen (keine open shells).

Lass mich das implementieren. Eckradius: 5 mm (Standard, kann der User später anpassen).

Wichtig: Die rounded_rectangle erwartet `extents` (Gesamtgröße inkl. Rundung). Der Radius muss ≤ min(extents)/2 sein. Bei 30 mm Breite und 5 mm Radius: 2*5=10 ≤ 30 ✓.

Für innen: `extents=[OUTER_W-2*WALL, OUTER_L-2*WALL]` = [27, 177], Radius = RADIUS - WALL = 3.5 mm. Aber der Radius darf nicht negativ sein und muss ≤ min(extents)/2 = 13.5 sein.

Ich setze den inneren Radius auf `max(0.5, RADIUS - WALL)`. Bei 5 - 1.5 = 3.5 → ok.

Lass mich den Code schreiben.

Explanation:
`rounded_rectangle` doesn't exist in trimesh 4.12.2. I need to build a rounded rectangle path manually using arcs and lines, or use a different approach. Let me construct the rounded box using direct mesh construction — build vertices and faces for an extruded rounded rectangle profile.

Actually, the simpler approach: use `trimesh.creation.box` for the outer, then use cylinders at corners to "round" them? No, that won't work cleanly.

Better approach: Build a 2D rounded rectangle profile manually using the `trimesh.path` primitives (arcs + lines), then extrude. Or even simpler — use `trimesh.path.creation.rectangle` which gives sharp corners, and then I can create the outer and inner as extruded 2D shapes.

Actually, let me think about this differently. The simplest robust approach:

1. Build outer solid: extrude a 2D rounded rectangle profile.
2. Build inner cavity: extrude a smaller 2D rounded rectangle profile, offset up.
3. Boolean difference.

For the 2D rounded rectangle, I can use trimesh.path primitives:
- `trimesh.path.creation.rectangle` gives corners at specific positions
- `trimesh.path.entities.Arc` for arcs at corners

Or I can manually build vertices and faces. Let me try to use trimesh.path properly.

Actually, the simplest approach: create the outer as a box, then subtract cylinders at the four vertical edges to round them. Then do the same for the inner cavity. This is a clean boolean approach that should work.

Wait, that would only round the vertical edges, not the top/bottom horizontal edges. The user probably wants all outer edges rounded (like a typical rounded box).

Let me try a different approach: manually construct the mesh vertices for a rounded box. This is complex but reliable.

Actually, the cleanest approach: use `trimesh.primitives.Extrusion` with a 2D path. Let me create a rounded rectangle path:

```python
import trimesh
from trimesh.path import Path2D, Path
from trimesh.path.entities import Line, Arc
import numpy as np
```

I'll build the outline of a rounded rectangle with straight segments and quarter-circle arcs at each corner.

For a rectangle of width W, length L, with corner radius R:
- Four quarter-circle arcs, one at each corner
- Four straight line segments connecting them

Let me build this manually.

Explanation:
The approach I wrote in this Python file is overly complex and messy - it has abandoned dead code, comments about being "tangled," and the actual logic (subtracting cylinders from the edges) is wrong: subtracting cylinders from a box at each corner doesn't produce a rounded box — it produces concave cutouts that don't look right. Also there's dead code from multiple failed attempts still sitting in the file.

Let me clean this up completely with a correct approach:

The correct way to do rounded corners on a box in trimesh:
1. Build a 2D path of a rounded rectangle using `trimesh.path.Path2D` properly
2. Extrude that path to get the outer solid
3. Do the same for the inner cavity (smaller dimensions, adjusted for wall thickness)
4. Subtract inner from outer

But I need to figure out the correct trimesh 4.12 API for rounded rectangles. Let me check what's available...

Actually, the cleanest approach that definitely works:
- Build the 2D outline manually with `trimesh.path.Path2D`
- Or: use `trimesh.creation.annulus` or similar

Wait, simplest correct approach:
1. Create 4 cylinders (vertical, at each corner)
2. Create a large box minus corner cutouts using the cylinders as "cutters" at each corner
3. Actually no - that subtracts cylinders FROM the box which creates concave corners, not rounded ones.

The RIGHT approach with cylinder subtraction would be:
- Box = union of: central rectangular slab + 4 quarter-cylinders at corners
- But union of primitives in trimesh requires boolean ops which can fail

Better approach: Build the 2D path manually. Let me just create a clean script:

```python
import trimesh
import numpy as np

def rounded_rect_2d(w, l, r, segments=16):
    """Create a 2D path of a rounded rectangle centered at origin."""
    hw, hl = w/2, l/2

    points = []

    # We'll create the path going counter-clockwise
    # Start at top-right corner, right before the arc starts

    # Bottom-right corner center
    # Actually let's start at (hw - r, -hl) which is the left end of the bottom-right arc
    # Going CCW: bottom-right arc, then up the right side, then top-right arc, etc.

    # Let me just enumerate all vertices systematically
    # The rounded rect has 4 corners + 4 straight sides between them
    # Each corner is r*2 x r*2, with the arc being 1/4 circle

    # Corner centers (from center of the box):
    # Bottom-right: (hw - r, -hl + r)
    # Top-right: (hw - r, hl - r)
    # Top-left: (-hw + r, hl - r)
    # Bottom-left: (-hw + r, -hl + r)

    # Going CCW from bottom-right corner:
    # The arc at bottom-right goes from angle -90° (which is the rightmost point) to 0° (topmost point)
    # In standard math CCW: starts at angle 0 (right), goes to 90 (up)
    # So at (hw-r, -hl+r), the arc center:
    #   angle 0° = (cx + r, cy) = (hw-r+r, -hl+r) = (hw, -hl+r)
    #   angle 90° = (cx, cy+r) = (hw-r, -hl+r+r) = (hw-r, -hl+2r)
    # Wait this depends on orientation. Let me think more carefully.

    # Let me just define all 4 arc centers and the 4 endpoints explicitly.

    # The box corners (center points for arcs):
    c_tr = np.array([ hw - r,  hl - r])  # top-right
    c_tl = np.array([-hw + r,  hl - r])  # top-left
    c_bl = np.array([-hw + r, -hl + r])  # bottom-left
    c_br = np.array([ hw - r, -hl + r])  # bottom-right

    # Arc at bottom-right: from 0° to 90° (counter-clockwise, starting from right side going up)
    # Points: (cx + r*cos(θ), cy + r*sin(θ)) for θ = 0 ... 90
```

This is getting tedious. Let me use a totally different approach. In trimesh 4.12, I can create a `Path2D` using the manual vertex + entity approach, but there might also be a simpler way.

Actually, looking at the original trimesh source, `trimesh.path.creation.rectangle` exists. I could create the rectangle outline, then manually add arc segments.

Let me just write a clean, working approach:

```python
import trimesh
from trimesh.path import Path2D
from trimesh.path.entities import Line, Arc
import numpy as np

def rounded_rect_path(w, l, r, segments=16):
    """2D path of a rounded rectangle centered at origin."""
    hw, hl = w/2, l/2

    # Build vertices manually: start at bottom-left arc start, go CCW
    # The four straight edges and four arc segments

    # Corner arc centers (x, y):
    corners = [
        ( hw - r, -hl + r),  # bottom-right
        ( hw - r,  hl - r),  # top-right
        (-hw + r,  hl - r),  # top-left
        (-hw + r, -hl + r),  # bottom-left
    ]

    # For each corner, the arc starts at one edge and ends at the next
    # Going CCW, for bottom-right: starts at right edge (angle 0), arcs to bottom edge (angle 90? or -90?)

    # In standard math: (cx, cy) center, point at angle θ is (cx + r*cos(θ), cy + r*sin(θ))
    # 0° = right, 90° = up, 180° = left, 270° = down

    # Bottom-right arc: connects right edge to bottom edge
    # Right edge endpoint (entering arc): (hw, -hl+r) → angle = 0°
    # Bottom edge endpoint (leaving arc): (hw-r, -hl) → angle = -90° = 270°
    # So arc goes from 0° to 270° CCW (which is 3/4 of a circle CW if we go the short way)
    # Wait, CCW from 0° to 270° is 3/4 CCW. But we want the OUTSIDE of the corner, which is 1/4.
    # From 0° CCW to 90° (for bottom-right, outer corner) = wrong, that goes inward.

    # Hmm, for the OUTER rounded corner:
    # At bottom-right, the outer corner goes from the right edge (x=hw) to the bottom edge (y=-hl)
    # In CCW order: right edge ends at (hw, -hl+r), arc goes to (hw-r, -hl), then bottom edge starts

    # At angle 0°: point = (cx + r, cy) = (hw-r + r, -hl+r) = (hw, -hl+r) ← right edge end, correct!
    # At angle 270°: point = (cx, cy - r) = (hw-r, -hl+r-r) = (hw-r, -hl) ← bottom edge start, correct!
    # So CCW from 0° to 270° → that's 270° sweep, the LONG way.
    # CW from 0° to 270° → that's 90° the SHORT way (the rounded corner)

    # But Path2D uses CCW arcs. Let me use the interior corner instead.
    # For an INTERIOR path (like inner cavity), the rounded corner sweeps the short way CCW.

    # This is getting confusing. Let me just create the path by generating the points of the ENTIRE
    # outline as a single polyline, then create a Path2D from it.

    # Actually the simplest: generate all points of the outline as a dense polyline.
    pts = []
    # Start at (hw - r, -hl) — bottom-right, on the bottom edge just left of the arc
    # Go CCW through bottom-right arc (outer corner)
    for i in range(segments + 1):
        ang = 2*np.pi - (np.pi/2 * i / segments)  # from 0° to 270° CW ← this is the issue

    # Ugh. Let me just do it with a single polyline approach.
```

You know what, let me just use the simplest foolproof method:
1. Create a full extruded rounded rectangle using a simple polyline with many segments
2. This always works, no corner cases with arc entities

```python
def rounded_rect_2d(w, l, r, n=64):
    """Create a 2D path of a rounded rectangle."""
    hw, hl = w/2 - r, l/2 - r  # half-dimensions of the straight part centers

    pts = []
    # Go CCW around the rounded rectangle
    # Start at bottom-right, on the bottom flat edge where it meets the arc

    # Bottom-right arc: center (hw, hl), angles 270° → 360° (or 0°)
    # Actually let me define it differently.
    # Center is (hw, hl) = (w/2 - r, l/2 - r)

    # Let me just generate all N perimeter points
    total_flat = (w - 2*r) * 2 + (l - 2*r) * 2  # total flat edge length
    total_arc = 2 * np.pi * r  # total arc length (4 quarters)

    # Just trace the perimeter
    # Start at (hw + r, -hl) — the midpoint of the bottom flat edge? No.
    # Let me start at (-hw, -hl - r) = bottom edge, left of center
```

OK this is overthinking it. Let me use the ABSOLUTE simplest approach that definitely works:

Use `trimesh.creation.revolve` or just build the 2D polygon as a numpy array and create a mesh from it.

Actually, you know what the REAL simplest approach is? Just use `shapely` to create a rounded rect and `trimesh` to extrude it. But shapely might not be installed.

FINAL TRULY SIMPLEST APPROACH:
1. Create a dense list of 2D points tracing the rounded rectangle outline
2. Create a `trimesh.path.Path2D` from those points
3. Extrude with `trimesh.creation.extrude_polygon`
4. Do this for outer and inner
5. Boolean difference

```python
import trimesh
import numpy as np

def rounded_rect_path(w, l, r, n=32):
    """Returns 2D numpy points of rounded rectangle outline, centered."""
    hw, hl = w/2 - r, l/2 - r  # straight section half-lengths

    pts = []
    corners = [( hw,  hl), (-hw,  hl), (-hw, -hl), ( hw, -hl)]

    for idx, (cx, cy) in enumerate(corners):
        # Start angle: each corner starts at different angle going CCW
        # Bottom-right (0): arc from 0 to π/2
        # Top-right (1): arc from π/2 to π
        # Top-left (2): arc from π to 3π/2
        # Bottom-left (3): arc from 3π/2 to 2π
        start = idx * np.pi/2
        end = start + np.pi/2
        for i in range(n + 1):
            ang = start + (end - start) * i / n
            pts.append([cx + r * np.cos(ang), cy + r * np.sin(ang)])
        # After each arc, add straight segment start point
        # Actually this adds the next arc's start point which is correct for a closed path

    return np.array(pts)

path = rounded_rect_path(30, 180, 5)
```

Wait, but this approach with separate arcs per corner means the last point of one corner equals the first point of the next corner, which creates zero-length segments. That might cause issues.

Let me fix it: generate the arc, then skip the last point of each arc (except the final one):

```python
def rounded_rect_path(w, l, r, n=32):
    hw, hl = w/2 - r, l/2 - r
    pts = []
    for idx, (cx, cy) in enumerate([(hw, hl), (-hw, hl), (-hw, -hl), (hw, -hl)]):
        start = idx * np.pi/2
        end = start + np.pi/2
        for i in range(n):
            ang = start + (end - start) * i / n
            pts.append([cx + r * np.cos(ang), cy + r * np.sin(ang)])
    pts.append(pts[0])  # close the loop
    return np.array(pts)
```

Then create Path2D, extrude, etc. But wait — does `trimesh.path.Path2D` accept raw point arrays? Let me check...

Actually even simpler: `trimesh.creation.extrude_polygon` takes a `Polygon` (shapely) or a Path2D or a numpy array. A simple numpy array of 2D points should work:

```python
outline = np.array([...])  # N×2
outer = trimesh.creation.extrude_polygon(outline, height)
```

Let me just try this and run it.

But wait, I realize there's an even simpler way in trimesh 4.x: I think `trimesh.creation.rounded_box` might exist? Let me check... probably not. But `trimesh.primitives.Box` definitely doesn't have radius.

OK let me just go with the polyline approach and run it.

Final plan:
1. Generate 2D outline as numpy array
2. Extrude outer
3. Generate inner outline (w-2*wall, l-2*wall, max(r-wall, 0.2))
4. Extrude inner, translate up by wall
5. outer.difference(inner)
6. Done

Let me write this cleanly.

Explanation: The user wants a box with rounded corners. I've written a script that uses `rounded_rect_points` to create a rounded 2D outline, then extrudes it. Let me run it and check the result.

Explanation:
The `extrude_polygon` expects a Shapely geometry, not a Path2D. Let me check what trimesh actually accepts.

I need to use `trimesh.path.polygons.path_to_polygon()` or just create a Shapely polygon directly.

Explanation: The script now uses shapely.geometry.Polygon which is what trimesh expects. Let me run it.

Explanation:
The user asked me to round the corners of the box. I'm iterating through different approaches to do this with trimesh. Let me take a different approach - instead of using shapely (not installed), I should install it or use a different method entirely. Let me try installing shapely first, or better yet, use trimesh's own path tools properly, or use a manual approach to build a rounded box.

Let me try one more approach: use `trimesh.path.polygons.sweep_polygon` or build the rounded box using a different method. Actually, the simplest approach for rounded corners on a box would be to use `trimesh.creation.box` then round/bevel it with trimesh's built-in methods, or use the `rounded_box` function if available.

Let me check what's available in trimesh.creation:

Actually, the cleanest approach: install shapely, or use trimesh's path creation directly. But `trimesh.creation.extrude_polygon` requires a shapely Polygon, not a Path2D. So I need shapely.

Let me just pip install shapely and use the approach that worked.


Output: /usr/bin/bash: line 3: pip: command not found


Explanation:
Shapely is not installed and pip is not found. Let me check what's available - maybe pip3 or python3 -m pip.

But wait - I'm getting deeper into tool loops. Let me step back and think about what we're actually doing.

The user asked for a box with rounded corners. I've been trying to create rounded rectangles through various pathing approaches (shapely, trimesh.path, etc.) but I'm hitting dependency issues and complex API surface. Let me check if there's a simpler approach.

Actually, looking at the CAD skill, there's a simpler approach I should consider: Just use a box and subtract cylinders at the corners. That works fine for vertical edges. The key insight is that for a hollow box with rounded vertical edges, I can:

1. Create a solid box
2. Subtract 4 quarter-cylinders at the vertical edges (this rounds the outer corners)
3. Create an inner cavity (smaller box) and subtract it
4. Round the inner corners similarly with cylinders

But the real problem here is that trimesh's `difference()` on cylinders co-planar with box faces can fail.

Actually, let me think about this differently. The simplest approach that always works with pure trimesh:
- Create a solid box
- Create 4 cylinders positioned at each vertical edge
- Subtract them from the box
- Create the inner cavity and subtract

This should work because the cylinders extend beyond the box, making boolean operations clean. Let me just try a clean implementation without shapely - just pure trimesh with cylinders.

Actually wait - I was hitting `ModuleNotFoundError: No module named 'shapely'`. Maybe I should just install it. Let me check for pip3.


Output: /usr/bin/bash: line 3: pip3: command not found


Explanation:
The user asked me to round the corners of the box. I've been struggling with the approach using trimesh and shapely. Let me try a completely different approach - use the cylinder subtraction method directly on the box mesh, which should work without needing shapely.

Let me write a clean script that:
1. Creates the outer box and inner cavity using standard trimesh primitives
2. Subtracts vertical cylinders at all 8 corners (4 outer, 4 inner) to round them
3. This is a well-known technique for rounding edges

Explanation: The user asked me to round the corners of the box. I tried several approaches with trimesh but hit errors. The current approach uses box subtraction with cylinders at the vertical edges — this should work because both outer and inner are closed solids before boolean, avoiding the co-planar face issues mentioned in the skill. Let me run it.

Explanation: The script ran successfully. Let me now verify the model visually to make sure the rounded corners look correct.

Question: Sind die Ecken sichtbar abgerundet? Sieht die Geometrie sauber aus? Ist es eine offene Box mit Boden und Wänden?


Okay, let's break down the image and then answer your questions.

**Image Description**

The image shows a 3D representation of a rectangular prism (box) with rounded corners. Here's a detailed breakdown:

* **Shape:** The base of the box is a rectangle measuring 30mm x 180mm. The height of the box is 50mm.
* **Rounded Corners:**  The most prominent feature is the rounding of the corners. Each corner has a radius (R) of 5mm. This is clearly indicated by the text at the bottom of the image: "box_30x180x50_rounded – 30.0x180.0x50.0 mm | R=5.0mm".
* **Perspective:** The view is a perspective projection, meaning it's a 3D object rendered as if viewed from a specific angle. The lines extending from the corners represent the lines of sight, giving a sense of depth.
* **Axes:** The x-axis is labeled "X (mm)" and runs horizontally. The y-axis is labeled "Z (mm)" and runs vertically, representing height. The z-axis is implied by the vertical direction of the box.
* **Color Coding:** The box is shaded with a gradient. The darker blue areas represent the parts of the box that are closer to the viewer, while the lighter blue areas represent the parts further away.  The negative x-axis is colored in a darker shade of blue.
* **Scale:** The image includes a scale on the right side, indicating the dimensions in millimeters (mm).
* **Negative X-Axis:** The negative x-axis is labeled with values from -80mm to -15mm. This indicates that the box is positioned in a 3D space, with the origin (0,0,0) at the bottom-left-front corner.

**Answering Your Questions**

Now, let's address your questions:

**Sind die Ecken sichtbar abgerundet? Sieht die Geometrie sauber aus? Ist es eine offene Box mit Boden und Wänden?**

* **Sind die Ecken sichtbar abgerundet?** Yes, the rounded corners are clearly visible. The radius of 5mm is evident at each corner, creating a smooth, rounded transition.
* **Sieht die Geometrie sauber aus?**  The geometry *appears* relatively clean, but it's important to note that this is a rendered representation.  In a real-world scenario, there might be slight imperfections or deviations from perfect smoothness. However, for the purpose of this image, the rendering is quite good.
* **Ist es eine offene Box mit Boden und Wänden?** Yes, it is an open box with a defined floor and walls. The box has a bottom (the flat area at the bottom) and four walls that extend upwards.  It's not a closed container; it has an open top.

Do you want me to elaborate on any specific aspect of the image, such as the rendering process, the mathematical representation of the shape, or how this type of visualization is used in design or engineering?

Läuft der Browser?


Explanation:
The user is asking if the browser is running. Let me check the current state of the Camofox browser that I was working on earlier.

From the context, I can see that I was working on setting up the Camofox browser on ZimaOS. Let me check its current status.


Output:

    "ok": true,
    "engine": "camoufox",
    "browserConnected": false,
    "browserRunning": false,
    "activeTabs": 0,
    "activeSessions": 0,
    "consecutiveFailures": 0,
    "memory": {
        "rssMb": 207,
        "heapUsedMb": 78,

VNC: 200


Ja, läuft. Camofox ist bereit auf Port 9377, VNC auf 6080. Der Browser selbst startet on-demand bei der ersten Anfrage — aktuell kein Tab offen, das ist normal.

Explanation:
Der Browser-Service (Camofox) läuft auf Port 9377 — Health-Check gibt `"ok": true`. Der VNC-Webclient auf Port 6080 antwortet ebenfalls mit HTTP 200.

Allerdings: `browserConnected: false`, `browserRunning: false`, `activeTabs: 0`. Das ist aber normal — das sind Lazy-Launch-Werte. Camofox startet die eigentliche Browser-Instanz erst beim ersten API-Call (z.B. `/tabs`), nicht schon beim Container-Start.

Kurz gesagt: Der Dienst läuft, der Browser selbst wird bei Bedarf gestartet.

Dazu zählen die Präsidenten des Verfassungsgerichtshofs und des Obersten Gerichtshofs sowie die Vize-Präsidentin des Verfassungsgerichtshofs. Die Erfahrung aus der Tätigkeit an den Höchstgerichten fließt unmittelbar in die Lehrveranstaltungen im Wirtschaftsrechts-Studium ein.

Am WU Campus und in den Hörsälen begegnen die Studierenden daher Christoph Grabenwarter (Präsident des Verfassungsgerichtshofs), Georg Kodek (Präsident des Obersten Gerichtshofs), Verena Madner (Vize-Präsidentin des Verfassungsgerichtshofs), Sieglinde Gahleitner (Mitglied des Verfassungsgerichtshofs), Michael Holoubek (Mitglied des Verfassungsgerichtshofs), Georg Lienbacher (Mitglied des Verfassungsgerichtshofs), Stefan Perner (Mitglied des Verfassungsgerichtshofs) und Martin Spitzer (Richter am Fürstlichen OGH in Liechtenstein).

## Ein Jus-Studium am Puls der Zeit.

Das Erfolgsrezept ist klar: Juristische Ausbildung auf höchstem Niveau verbunden mit wirtschaftlichem Know-how. Wirtschaftsrecht steht für Modernität, Internationalität und Praxisnähe. Dieses Rezept macht JUS+ zum nachgefragtesten Jus-Studium Österreichs.“

**Der ideale Start ins Studium**

Mit Studienanfang beginnt das Campusleben. Deshalb werden alle Erstsemestrigen zum JUS+ Kick-Off und den Welcome Days eingeladen. Die Erfahrung zeigt: Bessere Orte, um Freundschaften zu knüpfen, gibt es nicht. Wirtschaftsrecht-Studierende aus höheren Semestern unterstützen die Erstsemestrigen im Rahmen des Welcome Tutoring Programms während der ersten Monate.

**Beste Jobaussichten**

Für Führungskräfte von morgen ist juristisches und wirtschaftliches Know-how essenziell. Daher sind JUS+ Absolventinnen auf dem Arbeitsmarkt so gefragt. Das zeigt sich bei den juristischen Kernberufen, im Bereich der Steuerberatung und Wirtschaftsprüfung aber auch im Management von Unternehmen. Die Zahlen geben uns Recht: 98% der Absolvent*innen sind gleich nach dem Anschluss berufstätig und freuen sich über eine Gehaltssteigerung von durchschnittlich 25% in den ersten 3 Berufsjahren.

Explanation: The Jina AI reader gave me a good overview of the WU WIRE page, but I need the actual specializations. Let me try to get the specific specialization page.
