Worm drive generator
Generate a worm drive (worm + worm wheel, high reduction, often self-locking)
A worm meshing a worm wheel at 90° — compact, high-reduction, and often self-locking. Set the module, wheel teeth, and the number of worm starts, and the reduction, lead angle, and centre distance are derived as you go. Download a print-ready STL or 3MF.
