-    FireFly tetrahedron adapter
-    Base STL: tetrahedron40mmC.stl
-
-    Purpose:
-    - Import original 40 mm foldable tetrahedron STL
-    - Scale it to 60 mm base geometry
-    - Add cable holes, vent/drain holes, and optional PCB mounting holes
-
-    Workflow:
-    1. Set PART = "upper"
-    2. Render with F6
-    3. Export STL
-    4. Set PART = "lower"
-    5. Render with F6
-    6. Export STL
-
-    Notes:
-    - Hole coordinates are defined on the original 40 mm STL coordinate system.
-    - The script scales them automatically to 60 mm.
-    - First export should be treated as v0.1 prototype.
