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.

3MF Gear Generator StarForge 3D Modeling Software

Involute Spur Gears Without CAD

Millimetre units travel inside 3MF, the zipped XML 3D Manufacturing Format, so a gear opened in Bambu Studio, PrusaSlicer or Orca Slicer lands at its true size with no scale guessing. The 3MF Gear Generator builds involute spur gears from a module, a tooth count and a bore, then adds a mate and turns both on screen at the exact centre distance, outlines checked so they never cross. Every gear uses a 20 degree pressure angle with 0.15 mm backlash. StarForge 3D Modeling Software also offers each one as a 3D Print STL File, ready for 3D printing without CAD.
