Hallo Kiwi


Hallo Ahmed! 👋

Alles klar bei dir? Was haben wir heute auf dem Zettel?

Explanation:
The user greeted me with "Hallo Kiwi". Looking at my memory, there's a very important note:

"User is Ahmed Zeyd Aytac. He refers to me as 'Kiwi' and explicitly corrected me when I mistakenly called him 'Kiwi' — that is not his name."

So the user (Ahmed Zeyd Aytac) is calling ME "Kiwi". That's my nickname/what he calls me. I should respond naturally to this greeting.

I should say hello back. I don't need to load any skills for a simple greeting.


Wie ist das Wetter heute?

# CAD 3D Print Skill
## Purpose
Design printable 3D parts using CadQuery (Python parametric CAD) and export STL/STEP files. Optimized for Bambu Lab A1 Mini (180×180×180 mm, 0.4 mm nozzle).
## When to Use
Use this skill whenever the user asks to design, model, modify, or export a 3D part for printing.
## Workflow
1. Understand the part: dimensions, function, tolerances
2. Write CadQuery Python code using the template below
3. Save code to /DATA/AppData/hermes/Projekte/3d/<name>.py
4. Execute: terminal("cd /DATA/AppData/hermes/Projekte/3d && python <name>.py")
5. Verify output exists, check dimensions fit A1 Mini
6. Report file path and print recommendations
## Output Directory
/DATA/AppData/hermes/Projekte/3d/
Always export both STL (for Bambu Studio) and STEP (for future edits).
## Standard Code Template
```python
import cadquery as cq
import os
OUTPUT_DIR = "/DATA/AppData/hermes/Projekte/3d"
os.makedirs(OUTPUT_DIR, exist_ok=True)
NAME = "my_part"  # change per model
# ─── MODEL ────────────────────────────────────────────────
result = (
    cq.Workplane("XY")
    .box(40, 30, 20)  # replace with actual geometry
)
# ──────────────────────────────────────────────────────────
# Validate bounds
bb = result.val().BoundingBox()
assert bb.xlen <= 180 and bb.ylen <= 180 and bb.zlen <= 180, \
    f"Exceeds A1 Mini build volume: {bb.xlen:.1f}×{bb.ylen:.1f}×{bb.zlen:.1f} mm"
# Export
stl_path = f"{OUTPUT_DIR}/{NAME}.stl"
step_path = f"{OUTPUT_DIR}/{NAME}.step"
cq.exporters.export(result, stl_path)
cq.exporters.export(result, step_path)
print(f"✅ {NAME}: {bb.xlen:.1f} × {bb.ylen:.1f} × {bb.zlen:.1f} mm")
print(f"   STL  → {stl_path}")
print(f"   STEP → {step_path}")

Explanation:
The user wants me to execute their commands in a very specific way. They want:

Step 1: Create directories (done above)
Step 2: Install CadQuery in background with notify_on_complete=true
Step 3: Write the SKILL.md content exactly as provided

I already did step 1. Now I need to do step 2 (background terminal for pip install) and step 3 (write SKILL.md).

For step 2, I should use terminal() with background=true and notify_on_complete=true.

For step 3, I need to write the exact content to ~/.hermes/skills/cad-3d-print/SKILL.md.

Let me do both.


Output: Background process started


No linter for .md files


Step 1 ✅ Verzeichnisse erstellt.
Step 2 ⏳ **CadQuery wird im Hintergrund installiert** (session ID: `proc_7cd73b873153`).
Step 3 ✅ **SKILL.md geschrieben** nach `~/.hermes/skills/cad-3d-print/SKILL.md`.

Wir warten jetzt auf den `pip install`. Du bekommst eine Nachricht, wenn CadQuery fertig ist. 🚀

Explanation:
Step 1 done: Verzeichnisse erstellt.
Step 2 running: CadQuery wird im Hintergrund installiert (notify_on_complete=true).
Step 3 done: SKILL.md geschrieben.

Jetzt warte ich auf die Installation. Da notify_on_complete=true, werde ich automatisch benachrichtigt wenn das fertig ist.

Lass mich den Status prüfen und dem User den Zwischenstand geben.

bash: pip: command not found
]


Explanation: Ah, `pip` command not found because ZimaOS doesn't have pip on PATH. But Python venv exists at `/DATA/AppData/hermes/venv`. I need to use the venv's pip or python -m pip. Let me check what's available and install cadquery properly.

ls /DATA/AppData/hermes/venv/bin/python* && ls /DATA/AppData/hermes/venv/bin/pip*


Output:
/DATA/AppData/hermes/venv/bin/python
/DATA/AppData/hermes/venv/bin/python3
/DATA/AppData/hermes/venv/bin/python3.11
/DATA/AppData/hermes/venv/bin/pip3
/DATA/AppData/hermes/venv/bin/pip3.11


Aha — `pip` fehlt, aber `pip3` existiert. Retrying...

Explanation: Ah! `pip` is not found but `pip3` is. The venv has `pip3` not `pip`. I should retry using `pip3`. Let me use `pip3` to install cadquery.

pip3 install cadquery --prefix /DATA/AppData/hermes/venv


Output: Background process started


CadQuery wird jetzt mit **pip3** im Hintergrund installiert — die letzte Version hatte kein `pip` im PATH, nur `pip3`.

Sobald der Install fertig ist, bekommst du eine Nachricht und dann können wir direkt loslegen mit den ersten STLs. 🖨⏳

Explanation: <think>The pip3 install is running. I will wait for the background process to complete and then notify the user. Since the process is running in the background with notify_on_complete set to true, the system will automatically notify me when it's done. I don't need to do anything else right now except wait for that notification. I should inform the user that CadQuery installation is in progress via pip3.

bash: pip3: command not found
]


Explanation: Seltsam — `pip3` existiert im venv-Bin-Verzeichnis, aber `bash: pip3: command not found` im Terminal-Hintergrundprozess. Das bedeutet, der Hintergrundprozess hat wahrscheinlich nicht den venv im PATH. Ich muss den venv-Python direkt nehmen: `/DATA/AppData/hermes/venv/bin/python -m pip install cadquery` oder zumindest mit vollem Pfad zum pip3 Skript arbeiten.

Explanation: <think>Der Benutzer hat gerade nach dem Wetter gefragt. Ich bin auf einem ZimOS System. Ich werde das Wetter für Wien (Österreich) überprüfen. Es ist am Dienstag, 12. Mai 2026 Nachmittag. Lass mich das über ein Tool prüfen, wenn möglich, oder einfach eine allgemeine Vorhersage geben. Da ich kein spezifisches Wetter-Tool habe, sollte ich einen websuche oder einen API-Aufruf machen. Da wir auf einer Linux-Maschine sind, kann ich "curl wttr.in" verwenden, um schnell das Wetter zu bekommen.


Output: wien: ☁  +11°C

Command required approval (Security scan — [MEDIUM] Schemeless URL in sink context: URL without explicit scheme passed to a command that downloads/executes content) and was approved by the user.


Das Wetter in Wien ist heute bewölkt (☁) mit +11°C.

Willst du noch irgendetwas bestimmtes wissen oder etwas anderes machen?

Explanation:
Das Wetter in Wien ist heute bewölkt (☁) mit +11°C.

Soll ich noch irgendetwas tun? Ich habe den Benutzer gefragt, ob er noch etwas wissen möchte, aber er hat nicht geantwortet.


Skill fertig?


✅ **CadQuery ist erfolgreich installiert!** (exit code 0)

Schnelltest, ob es auch läuft:

Explanation: The user is asking about the skill. CadQuery installation is now complete (exit code 0). I should confirm this and then do a quick test to verify CadQuery actually works before declaring the skill fully ready.

cd /DATA/AppData/hermes/Projekte/3d && /DATA/AppData/hermes/venv/bin/python -c "import cadquery as cq; r = cq.Workplane('XY').box(10,10,10); print('OK:', r.val().BoundingBox().xlen, 'mm')"


Output:
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/DATA/AppData/hermes/venv/lib/python3.11/site-packages/cadquery/__init__.py", line 10, in <module>

    from OCP.OCP import *
ImportError: libGL.so.1: cannot open shared object file: No such file or directory


Explanation:
<think>Ah, `libGL.so.1` fehlt — das ist das gleiche Problem wie bei OpenSCAD/CadQuery AppImage (was wir schon in MEMORY.md dokumentiert haben). CadQuery basiert auf OpenCASCADE (OCP), was libGL braucht. Das ist ein headless Server ohne libGL.so.1.

Ich könnte libosmesa6-dev oder ähnliches (Software OpenGL) installieren, oder vielleicht gibt es einen anderen Weg. Aber da wir schon wissen dass CadQuery nicht laufen wird, muss ich einen alternativen Ansatz finden.

Längerfristig könnte ich den Skill auf **CadQuery2 oder Build123D** umstellen, die besser headless funktionieren könnten. Aber für jetzt: SKILL.md ist geschrieben und CadQuery installiert, es läuft aber nicht wegen libGL.

Optionen:
1. Skill auf trimesh/manifold umstellen (was wir schon haben funktionierend dokumentiert)
2. Build123D/CadQuery2 versuchen
3. libGL via OSMesa oder ähnlich installieren

Da der Skill schon als "CadQuery" gebaut ist und es tatsächlich installiert ist aber nicht läuft, sollte ich wohl:
- Einen schnellen Versuch mit OSMesa machen, um es funktionsfähig zu bekommen
- Oder den Skill auf trimesh umstellen, was wir wissen dass es funktioniert (siehe MEMORY.md)

Ich denke der beste Ansatz ist: SKILL.md auf **Build123D** oder **CadQuery + OSMesa/LLVMPIPE** umzustellen, oder eben auf **trimesh + manifold3d** was wir wissen dass es funktioniert.

Aber trimesh ist nicht wirklich CAD im klassischen Sinn. CadQuery ist viel besser für parametrische Modelle. Lass mich versuchen, libGL zu fixen.

Aber warte - in MEMORY.md steht:
"CadQuery AppImage and CadQuery fail due to missing libGL.so.1."

Das bedeutet es schlug schon vorher fehl. Wenn ich jetzt OSMesa installiere, könnte es funktionieren. Aber OSMesa ist ein großes Paket und erfordert root.

Alternativ: Wir haben schon `trimesh + manifold3d` dokumentiert als funktionierend. Aber der Skill soll CAD mit CadQuery sein.

Ich sollte jetzt ehrlich sein: CadQuery ist installiert, braucht aber libGL. Der Skill funktioniert erst, wenn libGL verfügbar ist.

Aber lass mich schauen, ob es einfach ist zu fixen:

apt list --installed 2>/dev/null | grep -i mesa || echo "kein mesa" ; ls /usr/lib*/libGL* 2>/dev/null || echo "kein libGL"


Output:
kein mesa
/usr/lib64/libGLESv1_CM.so
/usr/lib64/libGLESv1_CM.so.1
/usr/lib64/libGLESv1_CM.so.1.1.0
/usr/lib64/libGLESv2.so
/usr/lib64/libGLESv2.so.2
/usr/lib64/libGLESv2.so.2.0.0
/usr/lib/libGLESv1_CM.so
/usr/lib/libGLESv1_CM.so.1
/usr/lib/libGLESv1_CM.so.1.1.0
/usr/lib/libGLESv2.so
/usr/lib/libGLESv2.so.2
/usr/lib/libGLESv2.so.2.0.0


CadQuery braucht `libGL.so.1`, was auf deinem headless ZimaOS fehlt. Ich installiere jetzt die Mesa Software-Rendering-Bibliothek damit CadQuery läuft:

Explanation:
Das Problem ist offensichtlich: libGL.so.1 fehlt. ZimaOS ist ein headless Server-OS ohne X-Server / Display / Mesa. CadQuery (bzw. dessen OCP Bindings) braucht aber OpenGL wegen der VTK/Trame Abhängigkeit, auch wenn man es nur für headless CAD Modellierung verwenden will.

Ich muss entweder:
1. libGL.so.1 installieren (z.B. mesa-libGL oder ähnliches).
2. Oder einen Workaround finden, z.B. CAD-Modellierung via build123d oder FreeCAD als headless Alternativen.

Aber der Benutzer möchte wissentlich CadQuery. Also muss ich `libGL.so.1` installieren.

Auf Fedora/Rocky/RHEL (ZimaOS basiert darauf) wäre das Paket `mesa-libGL` oder `mesa-libGLU`. Lassen mich das probieren.

Aber warte - ZimaOS läuft im Container / NAS Container. Es gibt keine GPU und kein Display. Trotzdem können Software Rendering Libraries (libGL.so.1 via mesa) installiert werden, denn die .so kann auch via llvmpipe software rendering arbeiten, ohne echte GPU. Das würde CadQuery erlauben zu starten.

Ich sollte versuchen:
```
dnf install -y mesa-libGL
```
oder apt. ZimaOS scheint ein RPM-basiertes System zu sein. Lassen mich das testen.

cat /etc/os-release 2>/dev/null | head -5 ; which dnf yum apt apk


Output:
NAME="ZimaOS"
BOARD="ZimaCube"

ZimaOS hat keinen Paketmanager — `libGL.so.1` ist nicht installierbar. CadQuery braucht es aber zwingend für OCP (OpenCASCADE).

**Lösung:** Wir hatten das schon in der ersten Session herausgefunden — **trimesh + manifold3d** funktionieren headless und sind bereits installiert. Ich aktualisiere das Skill gleich auf manifold3d:

Explanation:
Ah — ZimaOS, keine traditionellen Package Manager verfügbar. libGL.so.1 fehlt komplett. CadQuery braucht aber libGL für den OCP-Import (OpenCASCADE).

Was sind meine Alternativen, um auf ZimaOS STL/STEP zu generieren, ohne libGL?

1. **trimesh** — funktioniert ohne GL! Habe ich bereits in MEIN MEMORY: "trimesh (v4.12.2) + manifold3d (v3.4.1) in /DATA/AppData/hermes/venv.". TRIMESH funktioniert headless.
2. **build123d** — gleiches OCP-Backend wie CadQuery, wird libGL auch fehlschlagen
3. **SolidPython** → OpenSCAD, aber OpenSCAD braucht libGL.so.1 (hatten wir schon mit AppImage)
4. **manifold3d** direkt — funktioniert bereits headless, kann STL exportieren
5. **CadQuery über offscreen / VirtualGL** → way too complex

Also die beste Option: **Skill auf trimesh/manifold3d umstellen**, statt CadQuery. Das hatten wir ja in der ersten Session schon herausgefunden.

Ich werde:
1. Das SKILL.md updaten, um trimesh+manifold3d anstatt CadQuery zu verwenden
2. Einen Testlauf machen mit manifold3d

Lass mich zuerst das Skill updaten.

Nicht ganz — CadQuery braucht `libGL.so.1` was auf ZimaOS nicht verfügbar ist. Wir nutzen stattdessen **trimesh + manifold3d**, die bereits funktionieren. Ich aktualisiere das Skill jetzt:

Explanation:
Der Nutzer will wissen, ob das Skill fertig ist. Ich habe gerade festgestellt, dass CadQuery wegen fehlendem libGL.so.1 auf ZimaOS nicht läuft. Ich muss das Skill umschreiben, um trimesh + manifold3d zu verwenden, die bereits funktionieren.

Ich werde das SKILL.md komplett umschreiben für trimesh+manifold3d statt CadQuery.

# CAD 3D Print Skill
## Purpose
Design printable 3D parts using **trimesh** + **manifold3d** (headless auf ZimaOS) and export STL files ready for Bambu Studio.
## Why trimesh + manifold3d?
- CadQuery erfordert libGL.so.1 → funktioniert **nicht** auf headless ZimaOS
- trimesh + manifold3d sind **bereits installiert** und laufen out-of-the-box
- manifold3d bietet boolesche Operationen, Extrusion, Revolve — alles was wir brauchen

# Boolean subtract (hole)
part = m3d.Manifold(mesh=part_mesh)
hole = m3d.Manifold(mesh=hole_mesh)
part_with_hole = part - hole

# Offset / Shell
thinned = part.offset(-1.0, 0)   # inward offset by 1 mm
```
## manifold3d API Quick Reference
- `m3d.Manifold(mesh=mesh)` — create from Mesh
- `manifold.to_mesh()` — export back to Mesh
- `manifold + other` — boolean union
- `manifold - other` — boolean difference
- `manifold ^ other` — boolean intersect
- `manifold.offset(delta, segments)` — offset surface
- `manifold.mirror(nx, ny, nz)` — mirror across plane
- `manifold.warp(fn)` — per-vertex warp function
## After Every Export — Always Tell the User
- ✅ File path: `/DATA/AppData/hermes/Projekte/3d/<name>.stl`
- Dimensions: X × Y × Z mm
- Print notes (supports? orientation? material?)
- "Open in Bambu Studio on your Mac to slice and send to the A1 Mini."

Explanation:
Das Skill funktioniert:
- CadQuery braucht libGL.so.1 → nicht verfügbar auf ZimaOS
- trimesh + manifold3d funktioniert headless
- Test-Box STL erfolgreich erstellt

Der Skill ist fertig. Ich sollte jetzt die Todos entsprechend updaten und dem User berichten.

## Resümee

| Schritt | Status | Details |
|---------|--------|---------|
| **1. Verzeichnisse** | ✅ | `~/.hermes/skills/cad-3d-print/` und `/DATA/AppData/hermes/Projekte/3d/` |
| **2. CadQuery installieren** | ⚠ Installiert, aber **läuft nicht** | Erfordert `libGL.so.1` — auf headless ZimaOS nicht verfügbar |
| **3. SKILL.md** | ✅ Aktualisiert | Wechsel auf **trimesh + manifold3d** |
| **4. Funktions-Test** | ✅ Bestanden | Testbox 40×30×20 mm erfolgreich als STL exportiert |

---

**Fazit:** CadQuery ist installiert aber nutzlos auf ZimaOS. Stattdessen nutzen wir **trimesh + manifold3d** — beide sind bereits im venv vorhanden, funktionieren headless und können boolesche Operationen, Offset, Spiegelung etc. Das SKILL.md spiegelt das jetzt korrekt wieder, inklusive vollständigem Code-Template, API-Referenz und Beispielen.

**Nächster Schritt:** Sag mir was du bauen willst und ich generiere sofort die Python-Datei + STL! 🖨

Explanation:
Alles fertig! Das Skill ist erfolgreich aufgesetzt:
1. ✅ CadQuery installiert (fail wegen libGL.so.1)
2. ✅ SKILL.md geschrieben und aktualisiert auf trimesh + manifold3d
3. ✅ Funktionstest bestanden: 40.0 x 30.0 x 20.0 mm Testbox erstellt und exportiert

Zeit für das Resümee.


Update the cad-3d-print skill to v2.0.0 with preview generation, mesh validation, 3MF export, FDM tolerances, and iteration support — all built on trimesh + manifold3d (no CadQuery). Steps:
Step 1 — Install matplotlib + lxml (matplotlib for PNG previews, lxml for 3MF export):
terminal("/DATA/AppData/hermes/venv/bin/pip install matplotlib lxml --prefix /DATA/AppData/hermes/venv", background=true, notify_on_complete=true)
Step 2 — Overwrite `~/.hermes/skills/cad-3d-print/SKILL.md` with the content between the markers:

version: 2.0.0
description: Parametric 3D modeling with trimesh + manifold3d for FDM printing on Bambu Lab A1 Mini. Generates STL+3MF with PNG preview and automatic mesh validation. Headless, pure Python, no GPU.

# CAD 3D Print Skill v2
## Purpose
Design printable 3D parts with trimesh + manifold3d, export STL+3MF for Bambu Studio, auto-generate PNG preview, validate mesh. Optimized for Bambu Lab A1 Mini (180×180×180 mm, 0.4 mm nozzle).
## Stack
- trimesh — primitives, I/O, transformations
- manifold3d — boolean engine (auto-selected when present)
- matplotlib — headless PNG preview (Agg backend)
## 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, print recommendations
## 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>.3mf, <name>.png

Decision Tree — "Make X" → Approach
Plate + holes → make_box + drill loop
Enclosure / project box → 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

print(f"  PNG: {png_path}")
print(f"  Watertight: {result.is_watertight}")
print(f"  Volume: {result.volume/1000:.1f} cm^3")
Step 4 — Run the test (after Step 1 install completes):
terminal("cd /DATA/AppData/hermes/Projekte/3d && /DATA/AppData/hermes/venv/bin/python test_bracket.py")

Step 5 — Report:

Confirm matplotlib + lxml install succeeded
Show first 10 lines of new SKILL.md (verify version 2.0.0)
Show test output (all 3 paths + watertight + volume)
Display test_bracket.png inline
Confirm skill is reloaded


Let's do it! Schrittweise:

**Step 1 + 2 parallel:** Installiere matplotlib + lxml und überschreibe das SKILL.md gleichzeitig.

Explanation:
The user wants me to update the cad-3d-print skill to v2.0.0 with several enhancements. They've provided very explicit steps. Let me break this down:

1. Install matplotlib + lxml in the venv
2. Overwrite the SKILL.md with the new content
3. Write test_bracket.py
4. Run the test
5. Report results

The user has provided very detailed content between the markers. Let me start with Step 1 (install matplotlib + lxml) and Step 2 (overwrite SKILL.md) in parallel, then wait for install to complete before running the test.

Let me also save the test file content in Step 3.

I should note that the SKILL.md content the user provided has some issues - the YAML frontmatter isn't properly closed and the content mixes YAML, markdown, and code blocks in ways that might not render well. But the user explicitly told me to overwrite with the content between the markers, so I'll do exactly that.

Wait, actually looking more carefully at the content, the SKILL.md format seems to be:
- YAML frontmatter (delimited by `---`)
- Markdown body with code blocks

But the content has the YAML frontmatter properly separated. Let me re-read...

Actually, the content starts with `---` and the frontmatter fields, then another `---`, then the markdown body. That looks correct for a SKILL.md file.

Let me proceed with the steps as requested.

terminal

/DATA/AppData/hermes/venv/bin/python -m pip install matplotlib lxml --prefix /DATA/AppData/hermes/venv


Output: Background process started


Install läuft im Hintergrund. Jetzt überschreibe ich das SKILL.md und erstelle die Testdatei parallel:

Explanation:
The user wants me to update the cad-3d-print skill to v2.0.0. The steps are:

1. Install matplotlib + lxml (background, already started)
2. Overwrite SKILL.md with the new content
3. Write test_bracket.py
4. Run the test
5. Report results

Step 1 is already running in background. I should proceed with Step 2 (write SKILL.md) and Step 3 (write test file) now, since they don't depend on the install completing.

Explanation: The SKILL.md was modified externally since I last read it. That means someone/something else edited it. Let me re-read it first before writing, to make sure I don't overwrite something important. Actually, I just wrote it earlier in this conversation, but the system says it was modified since I last read it. Let me just re-read to check current state.

Skill v2.0.0 ist geschrieben. Jetzt warte ich kurz auf die Package-Installation, bevor ich die Testdatei erstelle:

Explanation:
Skill ist jetzt v2.0.0 — bestätigt in den ersten Zeilen. Jetzt warte ich auf die Installation von matplotlib+lxml und schreibe danach die Testdatei. Ich kann aber schon die Testdatei schreiben, während der Install läuft... aber sie setzt matplotlib voraus. Also warten wir noch.

Ich schau mal ob der Background-Job noch läuft.


Der Hintergrundprozess ist bereits beendet. Ich erstelle jetzt die Testdatei und führe sie aus:

Explanation: Der Background-Prozess ist nicht mehr in der Liste — er ist bereits beendet (entweder erfolgreich oder so schnell, dass er schon aus der Liste verschwunden ist). Lass mich einfach die Testdatei schreiben und direkt laufen lassen.

import trimesh
import numpy as np
import matplotlib
matplotlib.use('Agg')
import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d.art3d import Poly3DCollection
import os

OUTPUT_DIR = "/DATA/AppData/hermes/Projekte/3d"
os.makedirs(OUTPUT_DIR, exist_ok=True)
NAME = "test_bracket"

LENGTH = 50
WIDTH = 30
THICKNESS = 4
HOLE_D = 3.2

plate = trimesh.creation.box(extents=[LENGTH, WIDTH, THICKNESS])
result = plate
for x in [-15, 15]:
    cyl = trimesh.creation.cylinder(radius=HOLE_D/2, height=THICKNESS*2, sections=48)
    cyl.apply_translation([x, 0, 0])
    result = result.difference(cyl)

bb = result.extents
stl_path = f"{OUTPUT_DIR}/{NAME}.stl"
mf_path  = f"{OUTPUT_DIR}/{NAME}.3mf"
png_path = f"{OUTPUT_DIR}/{NAME}.png"
result.export(stl_path)
mf_ok = True
try:
    result.export(mf_path)
except Exception as e:
    mf_ok = False
    print(f"3MF skipped: {e}")

fig = plt.figure(figsize=(8, 6))
ax = fig.add_subplot(111, projection='3d')
ax.add_collection3d(Poly3DCollection(result.vertices[result.faces], alpha=0.85, edgecolor='k', linewidth=0.15, facecolor='#7aa6d8'))

ax.set_title(f"{NAME} — {bb[0]:.1f}x{bb[1]:.1f}x{bb[2]:.1f} mm")
plt.savefig(png_path, dpi=110, bbox_inches='tight')

print(f"  PNG: {png_path}")
print(f"  Watertight: {result.is_watertight}")
print(f"  Volume: {result.volume/1000:.1f} cm^3")


Jetzt führe ich den Test aus:

Explanation: Die Testdatei ist geschrieben. Jetzt führe ich sie aus. Vorher schaue ich, ob matplotlib und lxml installiert sind. Da der Background process beendet war ohne Fehler (exit code?), ich schaue nochmal auf das Ergebnis. Da process list leer war und es bei mir lokal im Terminal keinen pip Fehler gab (der Background process hatte exit code 0), gehe ich davon aus, dass die Installation erfolgreich war. Jetzt führe ich den Test aus.

cd /DATA/AppData/hermes/Projekte/3d && /DATA/AppData/hermes/venv/bin/python test_bracket.py


Output:
mkdir -p failed for path /DATA/.config/matplotlib: [Errno 13] Permission denied: '/DATA/.config'
Matplotlib created a temporary cache directory at /tmp/matplotlib-kagcvmoh because there was an issue with the default path (/DATA/.config/matplotlib); it is highly recommended to set the MPLCONFIGDIR environment variable to a writable directory, in particular to speed up the import of Matplotlib and to better support multiprocessing.

AttributeError: 'TrackedArray' object has no attribute 'ptp'


Zwei Fixes nötig — `np.ptp()` statt `.ptp()` + `networkx` für 3MF. Fixe beides direkt:

Explanation: Der Fehler ist klar - `v[:,i].ptp()` funktioniert nicht in neueren numpy/trimesh Versionen. Ich muss `np.ptp(v[:, i])` verwenden. Das ist einfach zu fixen. Auch fehlt `networkx` für 3MF-Export. Wir müssen das beides fixen und den Test neu starten.

/DATA/AppData/hermes/venv/bin/python -m pip install networkx --prefix /DATA/AppData/hermes/venv


Output: Background process started


Jetzt fixe ich `test_bracket.py` für `.ptp()` und erstelle den matplotlib-Cache:

Explanation: Ich patche das test_bracket.py File, um `.ptp()` auf ein numpy-Array anzuwenden (statt `TrackedArray`), und erstelle gleichzeitig einen matplotlib-Config-Cache in einem beschreibbaren Verzeichnis.

✅ **Test bestanden!** STL, 3MF und PNG alle erfolgreich erstellt. Ich patche noch das `ptp`-Problem im SKILL.md Code-Template:

Explanation:
Das Testlauf hat funktioniert! STL, 3MF und PNG alle erfolgreich erstellt. Das netzwerk-Paket war bereits im Hintergrund installiert (erkennbar daran, dass 3MF jetzt NICHT mehr geskipped wurde, sondern erfolgreich exportiert wurde). Das ist perfekt.

Aber ich muss jetzt auch das SKILL.md anpassen:
1. Die `np.ptp()` statt `.ptp()` Änderung muss im SKILL.md Code-Template reflektiert werden
2. MPLCONFIGDIR-Tipp hinzufügen

Ich muss außerdem den SKILL.md-Code-Template finden und das `ax.set_box_aspect(...)` anpassen.

Lass mich das SKILL.md patchen.

Both 'target' and 'message' are required when action='send'


Explanation:
Ah, `send_message` braucht `target`. Auf Telegram kann ich einfach die `MEDIA:` Syntax direkt im Message-Body verwenden ohne `send_message` aufzurufen, oder ich muss `target` mitgeben. Lass mich das richtig machen.

Die Bildvorschau sende ich einfach direkt als Teil meiner Antwort — das ist die Standardmethode für Telegram. Ich kann keinen `target` bestimmen ohne `send_message(action='list')` aufzurufen, aber eigentlich ist meine Antwort an die aktuelle Konversation schon richtig und das Medien-Delivery passiert automatisch wenn ich `MEDIA:/path` in den Text packe.

...Aber `send_message` hat einen Fehler geworfen. Ich sollte also nicht explizit `send_message` aufrufen, sondern einfach die MEDIA-Referenz in meine normale Antwort einbetten. Das ist die Telegram-spezifische Semantik aus dem System-Prompt.

Ja klar — ich sollte einfach die MEDIA-Syntax in meinen Text schreiben. So kann ich keine getrennte send_message Anfrage machen, da das Tool einen `target` verlangt. Stattdessen integriere ich es in den normalen reply.

Design a storage box using the cad-3d-print skill.

Dimensions:
- Inner length: 85mm, inner width: 30mm, inner depth: 40mm (open top)
- Wall thickness: 3mm on all 4 sides
- Floor thickness: 10mm (total height = 50mm)
- Outer box = 91 × 36 × 50mm

Special: Round the 4 inner top opening edges with a 2mm chamfer.
Implement via: after subtracting the inner cavity, subtract a slightly larger box
(inner_length + 4mm × inner_width + 4mm × 2mm) at the very top of the opening —
this creates a beveled lead-in edge that removes the sharp corners a hand would touch.

Name the file: storage_box_85x30
Export STL


Explanation:
Der Benutzer möchte eine Lagerbox mit:
- Inner 85x30x40, offen oben
- Wanddicke 3mm auf allen Seiten
- Bodendicke 10mm, also Gesamthöhe 50mm
- Äußere Maße 91x36x50mm (85+6, 30+6)
- Chamfer: 2mm Abrundung innen oben
- Name: storage_box_85x30

Lass mich das SKILL.md laden und dann den Code schreiben.

## stack (headless on ZimaOS)
- trimesh — primitives, I/O, transformations
- manifold3d — boolean engine (auto-selected when present)
- matplotlib — headless PNG preview (Agg backend)
- networkx — **required** by trimesh for 3MF export
### 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 + manifold3d.
## 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, print recommendations
## 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>.3mf, <name>.png

    plate = drill(plate, x, y, 3.2)

# 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)
# 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
Plate + holes → make_box + drill loop
Enclosure / project box → 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, networkx needed, 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+manifold3d only. |
| `No module named 'networkx'` | networkx missing for 3MF export | `pip install networkx` before running. 3MF will silently fail otherwise. |
| `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. |
| Matplotlib permission warning | tries to write `~/.config/matplotlib` | Harmless; or set `MPLCONFIGDIR=/tmp/mpl` before running. |

Das Skill v2 ist geladen. Jetzt baue ich die Storage Box mit den exakten Spezifikationen.

Explanation:
Okay, das Skill ist fertig. Jetzt muss ich die `storage_box_85x30.py` Datei erstellen. Lass mich die Anforderungen brechen:

- Inner dimensions: 85×30×40 mm (open top)
- Wall thickness: 3mm (all 4 sides)
- Floor thickness: 10mm
- Total height: 50mm
- Outer box: 91×36×50mm (passt: 85+3+3=91, 30+3+3=36, 40+10=50? Hmm...)

Warte - die Anforderungen sagen:
- Inner depth = 40mm
- Floor thickness = 10mm
- Wall height = 40mm (inner depth + floor = 40? Oder floor thickness = 10 und die "Wand" ist 40mm hoch?)

Es scheint so:
- Die Box hat einen Boden von 10mm Dicke
- Die Wände sind 40mm hoch (da "open top" und "inner depth: 40mm")
- Total height = 50mm (10mm Boden + 40mm Wandhöhe)

Oder:
- Inner depth = 40mm (Innentiefe = Höhe der Hohlräume, also die Tiefe von oben nach unten)
- Floor thickness = 10mm
- Total height = 50mm

Also:
- Outer dimensions: 91 × 36 × 50 mm
- Inner dimensions: 85 × 30 × 40 mm (der "freie" Bereich über dem Boden von 10mm)

Special: 2mm chamfer at inner top opening edges. User beschreibt einen speziellen Ansatz:
> after subtracting the inner cavity, subtract a slightly larger box (inner_length + 4mm × inner_width + 4mm × 2mm) at the very top of the opening — this creates a beveled lead-in edge

Das ist ein interessantes Konzept. Wenn ich es richtig verstehe:
1. Outer box: 91 × 36 × 50
2. Subtract inner cavity: 85 × 30 × 40 (centered, sitting on top of floor)
3. Für den chamfer: subtract a box that ist wider than the opening by 4mm in x/y and 2mm deep in z, at the very top.

Warte, wenn der user sagt "subtract a slightly larger box (inner_length + 4mm × inner_width + 4mm × 2mm) at the very top of the opening" - das würde die sharp edges am oberen Rand entfernen und einen bevel/leadin schaffen.

Also:
- Inner cavity (main): 85 × 30 × 40 (von z=10 bis z=50)
- Chamfer cut: 89 × 34 × 2 (von z=48 bis z=50) - wait, das wäre 85+4=89, 30+4=34, und 2mm hoch

Hmm, die user sagt inner_length + 4mm × inner_width + 4mm × 2mm. Also die chamfer box hat die Maße 89 × 34 × 2.

Und sie wird auf top of the opening gesetzt - also bei z=48 bis z=50? Wenn die box 2mm hoch ist und am very top sitzt, dann wäre das von z=48 bis z=50? Wait no...

Der inner cavity ist 40mm hoch und startet bei z=10 (floor 10mm). Also das Opening ist von z=10 bis z=50. "Top of the opening" wäre bei z=50. Die chamfer box mit 2mm Höhe sitzt am very top → von z=48 bis z=50. Wait, aber wenn die chamfer box 2mm tief ist und am top sitzt, würde das die corners bei z=48-50 aufweiten.

Aber warte - wenn die inner cavity 85×30 ist, und die chamfer box 89×34 ist, dann wird die chamfer box über den Rändern hinaus gehen und diese cutten. Das entfernt die sharp edges und macht einen bevel.

Wie modelliert man das hier?
1. Outer box: 91 × 36 × 50
2. Inner cavity: 85 × 30 × 40, centered x/y, z=10 (so bottom at z=10, top at z=50)
3. Chamfer cut: 89 × 34 × 2, centered x/y, at z=48 (bottom z=48, top z=50)

Auch: ich brauche die make_box und die open_top_box-Funktionen die im Skill definiert sind.

In diesem Fall will der user einen open-top box, aber die open_top_box Funktion im Skill macht einen wandfester floor mit thickness=wall. Hier haben wir aber 10mm floor und 3mm walls. Also kann ich open_top_box nicht direkt verwenden - ich muss selbst bauen.

Das Modell:
1. Outer box: 91×36×50, centeriert
2. Inner cavity:
   - x: 85, y: 30, z: 40 (von z=10 bis z=50)
   - Centeriert in x/y: x=0, y=0, z=10+20=30? Nein.

Wenn ich make_box verwende, ist das Center bei (0,0,0) standardmäßig.
- Outer box: center (0,0,25), extents [91, 36, 50] → von x=-45.5 bis 45.5, y=-18 bis 18, z=0 bis 50
- Inner cavity: center (0,0,30)? Nein, der Boden ist bei z=10, die Höhe ist 40, also center bei z=10+20=30. extents [85, 30, 40] → z von 10 bis 50.
- Chamfer box: 89×34×2, center (0,0,49), extents → z von 48 bis 50.

Und dann:
final = outer - inner - chamfer

Nun, ich schreibe die Datei. Ich folge dem Skill-Template genau.

Storage Box fertig! 🎉

Ergebnisse:

- **Abmessungen**: 91.0 × 36.0 × 50.0 mm
- **Volumen**: 60.8 cm³ (nur das Solierteil)
- **Watertight**: True ✅
- **Innere Abmessungen**: 85 × 30 × 40 mm (Länge × Breite × Tiefe)
- **Wandstärke**: 3 mm
- **Boden**: 10 mm
- **Chamfer oben**: 2 mm × 2 mm Lead-in

Dateien:
- `/DATA/AppData/hermes/Projekte/3d/storage_box_85x30.py` (Quellcode)
- `/DATA/AppData/hermes/Projekte/3d/storage_box_85x30.stl`
- `/DATA/AppData/hermes/Projekte/3d/storage_box_85x30.3mf`

### Vorschau:

MEDIA:/DATA/AppData/hermes/Projekte/3d/storage_box_85x30.png

### Druck-Empfehlungen:

- **Orientierung**: Flacher Boden nach unten auf das Build Plate (91 × 36 mm Grundfläche)
- **Material**: PLA (indoor/dekorativ) oder PETG (strapazierfähiger)
- **Schichtdicke**: 0.2 mm Standard, 0.16 mm für glattere Flächen
- **Wandstärke**: 3mm ist perfekt für 3 Perimeter mit 0.4 mm Nozzle
- **Füllung**: 15-20% Grid reicht für eine Box dieses Volumens
- **Supports**: Keine nötig — alle Wände sind vertikal, der Chamfer ist nur oben und betrifft keine Überhänge
- **Print-Zeit ca.**: 2-3 Stunden bei 0.2 mm Layer

Öffne die `.3mf` in Bambu Studio — sie enthält Einheiten (mm) und Metadaten.

Möchtest du Änderungen? Zum Beispiel Wand dicker/dünner, Boden höher, oder ein Deckel dazu? 🛠

Explanation:
Der Code lief erfolgreich!
- Ergebnis: 91.0 × 36.0 × 50.0 mm (passt in den A1 Mini Build Volume)
- Volumen: 60.8 cm³
- Watertight: True
- STL, 3MF und PNG erstellt

Jetzt muss ich die Preview anzeigen. Ich habe zwei Optionen:
1. Mit `terminal` ein Bild anzeigen - geht nicht
2. In der Antwort `MEDIA:/DATA/AppData/hermes/Projekte/3d/storage_box_85x30.png` einbetten - das funktioniert mit Telegram

Ich werde das Bild inline einbetten und die Dateien auflisten.


Update the cad-3d-print SKILL.md at ~/.hermes/skills/cad-3d-print/SKILL.md with three changes:

CHANGE 2 — Replace the export/preview/report section of the Standard Code Template (everything after the bounds/validation check) with this — STL only, no 3MF, no STEP:

stl_path = f"{OUTPUT_DIR}/{NAME}.stl"
png_path = f"{OUTPUT_DIR}/{NAME}.png"
result.export(stl_path)

fig = plt.figure(figsize=(8, 6))
ax  = fig.add_subplot(111, projection='3d')
ax.add_collection3d(Poly3DCollection(
    result.vertices[result.faces], alpha=0.85, edgecolor='k',
    linewidth=0.15, facecolor='#7aa6d8'))
v = result.vertices
ax.set_xlim(v[:,0].min(), v[:,0].max())
ax.set_ylim(v[:,1].min(), v[:,1].max())
ax.set_zlim(v[:,2].min(), v[:,2].max())
ax.set_box_aspect([np.ptp(v[:,i]) for i in range(3)])
ax.set_xlabel('X (mm)'); ax.set_ylabel('Y (mm)'); ax.set_zlabel('Z (mm)')
ax.set_title(f"{NAME} — {bb[0]:.1f}x{bb[1]:.1f}x{bb[2]:.1f} mm")
plt.tight_layout()
plt.savefig(png_path, dpi=110, bbox_inches='tight')
plt.close()
print(f"OK {NAME}")
print(f"   Size:       {bb[0]:.1f} x {bb[1]:.1f} x {bb[2]:.1f} mm")
print(f"   Volume:     {result.volume/1000:.1f} cm3")
print(f"   Watertight: {result.is_watertight}")
print(f"   STL:        {stl_path}")
for w in warnings:
    print(f"   WARN: {w}")
CHANGE 3 — Replace the "After Every Export — Always Tell the User" section with this slimmed version:

## 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.
Also update the frontmatter description: field — remove any mention of 3MF, change to:
Parametric 3D modeling with trimesh + manifold3d for FDM printing. Generates STL with PNG preview and mesh validation. Headless, pure Python.

CHANGE 4 — Add the fillet warning note directly before the "Common Patterns" section:

⚠ Rounded edges: always use fillet_inner_top_edges() or open_top_box(..., fillet_r=2).
Never subtract a plain box as a chamfer — that creates a rectangular step, not a curve.

FINALLY — Regenerate /DATA/AppData/hermes/Projekte/3d/storage_box_85x30.py using the new helper.

Replace its MODEL block with:

box_body = open_top_box(OUTER_L, OUTER_W, OUTER_H, wall=WALL, fillet_r=2.0)
box_body.apply_translation([0, 0, OUTER_H/2])
result = box_body
Remove all 3MF export logic from that file too (STL + PNG only). Delete the old storage_box_85x30.3mf from disk.

Run the regenerated file, show the preview, confirm watertight. Report only: STL path, size, volume, watertight status. No print recommendations.


Ich mache das systematisch. Erst lade ich das aktuelle SKILL.md um die exakten Einfügepunkte zu finden:

Explanation:
Der Benutzer möchte mehrere Änderungen am Skill vornehmen und dann das storage_box_85x30.py neu generieren. Das ist ein komplexer Task mit vielen Schritten. Ich werde:

1. SKILL.md laden und verstehen
2. Die Änderungen nacheinander anwenden:
   - CHANGE 1: HELPER Block ersetzen
   - CHANGE 2: Export/preview/report Section ersetzen (STL nur)
   - CHANGE 3: Frontmatter description + After Every Export Section
   - CHANGE 4: Fillet Warning Note vor Common Patterns
3. storage_box_85x30.py neu schreiben mit neuem MODEL Block und ohne 3MF
4. Alte 3MF löschen
5. File ausführen
6. Preview zeigen
7. Report: nur STL path, size, volume, watertight

Ich sollte das mit Patch-Operationen machen. Lass mich zuerst die aktuelle SKILL.md lesen um die genauen Textstellen zu finden.
