Remove per-vertex colour data from CAD-exported STL/OBJ/GLB files. Cleaner geometry for downstream pipelines that don't accept vertex colours.

Some slicers (especially older Cura) get confused by vertex colour STL extensions. Engineering pipelines often expect bare geometry. CAD exports leak vertex colours unintentionally.
No — single-colour FDM/SLA printers ignore vertex colours anyway. Stripping them just cleans up the file.
Not in this tool. For colour-to-texture baking use Blender or Substance Painter.
Strip duplicate triangles and zero-area faces from STL/OBJ meshes. Smaller files, faster slicing, fewer printer errors.
Open toolRecompute consistent face and vertex normals on any STL/OBJ/GLB. Fixes inverted shading, missing normals, and flipped triangles.
Open toolFix problem STL meshes: weld duplicate vertices, remove degenerate faces, and detect non-manifold boundaries. Browser-based, zero upload.
