We just fixed downloads: every STL now comes straight from fast, reliable storage, saved under its own name, we're making 10,000 STL files and dozens of new tools, so things might break. We'll fix them ASAP.

IGES Polyhedron Maker StarForge 3D Modeling Software

Platonic Solids for School Workshop CAD

The Initial Graphics Exchange Specification is still read by older CAD and CAM packages in school workshops, and the IGES Polyhedron Maker hands them a faceted mesh rather than an exact parametric CAD solid. Its shapes are Platonic solids, a truncated icosahedron, a torus, a trefoil knot, a Menger sponge and a Sierpinski pyramid, solid or as a frame of 3 mm struts that is always one closed piece. StarForge 3D Modeling Software also saves a 3D Print STL File for 3D printing maths class models.
