STL, STEP check and convert on device.

ForgeShape opens STL, STEP, IGES, OBJ, GLB, and 3MF models on your device, finds what blocks printing — open edges, wrong normals, thin walls, overhangs — repairs it, and exports STL or 3MF for your slicer. It also converts between CAD and mesh formats. Nothing is ever uploaded.
