Planetary gearbox generator

Generate a planetary gearbox (sun + planets + ring)

Set the sun and planet tooth counts and the planet count, and the configurator derives the ring teeth, the reduction ratio, and whether the planets will actually assemble at equal spacing — live, before anything is printed. Download a print-ready STL or 3MF with the sun, planets, and ring as separate editable bodies.
