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.

STL Gear Generator StarForge 3D Modeling Software

Replacement Spur Gears Without CAD

Replacing a stripped gear in a toy, printer or kitchen appliance usually ends in an STL, the Stereolithography triangle mesh every slicer from Cura to Bambu Studio accepts. The STL Gear Generator draws involute spur gears from a typed module, tooth count and bore, adds a mate, and spins the pair on screen at the exact centre distance while checking the outlines never cross. A 20 degree pressure angle and 0.15 mm backlash mean any two gears of one module mesh. StarForge 3D Modeling Software saves each as a 3D Print STL File for 3D printing, no CAD needed.
