mesh3d

Create and edit 3D printable mesh files (STL, 3MF, OBJ) programmatically using Python trimesh + manifold3d. Use when the user asks to create 3D objects, modify existing STL/3MF files, add holes/features to meshes, combine or split meshes, repair meshes, convert between formats, analyze mesh geometry, or generate parametric parts for 3D printing. Triggers on "create STL", "make a 3D model", "edit mesh", "add hole", "modify STL", "3MF", "printable", "mesh repair", "boolean", "combine meshes", or any 3D modeling task that doesn't require a GUI CAD tool.
