Prompt that made this
Herringbone gear pair, meshed. Two separate parts, not grouped: a 15-tooth pinion and a 30-tooth gear, module 1.5, 14 mm face.
Made in Voloom from the prompt under the model. Sign in to download the STL, or fork it so every size on the right becomes editable — without spending credits.
Why this one
Compact 2:1 reduction stage with no net axial thrust, for FDM printing or machining
The two double-helix gears mesh on parallel shafts. The pinion is right-handed and the gear is left-handed, so the flanks mate and the opposing helix halves cancel axial thrust.
