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.

Involute Spur Gears for Legacy Pipelines

Colour 3D printing software and many older viewers still open the Virtual Reality Modeling Language as .wrl files, so the VRML Gear Generator serves legacy pipelines that never moved to newer formats. Each involute spur gear is defined by module, tooth count and bore, and an added mate spins at the exact centre distance with outlines checked never to cross. Gears share a 20 degree pressure angle and 0.15 mm backlash, so any two of one module run together in a toy, printer or appliance. StarForge 3D Modeling Software provides a 3D Print STL File for 3D printing too.
