Real involute gears: module, tooth count, pressure angle and helix are yours to set. Spur, helical or herringbone, with bore, keyway, hub and a matching pinion.
Free and without an account: type the numbers, watch the live preview, download STL and 3MF files that Bambu Studio, OrcaSlicer and PrusaSlicer open directly. Looking for a ready-made size? The model library has 651 of them, each with its dimensions already filled in.
Yes. They are true involute gears with the module, tooth count and pressure angle you type, so a pair generated with the same module meshes at the center distance the generator reports.
Spur gears are simplest and print cleanest. Helical gears run quieter but push sideways. Herringbone gears combine both halves and cancel the side thrust, and still print without supports.
Type the bore diameter and pick a keyed, D-shaped or hex bore; add a set screw boss if you want to lock it in place.
Your exact configuration is attached automatically, so the bug can be reproduced one-to-one. No account needed.
The machine that generates the models seems to be down or restarting. Your settings are safe in this tab: nothing is lost. Wait a moment and try again.
