Jetzt regeneriere ich die Storage Box mit dem neuen `open_top_box(..., chamfer=2.0)`:

Explanation: Das SKILL.md ist jetzt komplett umgeschrieben. Jetzt muss ich die `storage_box_85x30.py` mit dem neuen Skill-Template regenerieren — `open_top_box(..., chamfer=2.0)` statt der kaputten Boolean-Variante.

Explanation: Jetzt führe ich den Test aus:

mkdir -p /tmp/matplotlib-conf6 && export MPLCONFIGDIR=/tmp/matplotlib-conf6 && cd /DATA/AppData/hermes/Projekte/3d && /DATA/AppData/hermes/venv/bin/python storage_box_85x30.py


Output:

AttributeError: 'Trimesh' object has no attribute 'fix_faces'


Explanation: Kleiner Fehler: `fix_faces()` existiert nicht als Methode auf `Trimesh`. Das richtige ist `mesh.fix_normals()` oder manuell die Windung korrigieren. Lass mich das fixen und nochmal laufen lassen.
