Herringbone gear generator

Generate a herringbone gear (two opposite-hand helical halves)

Two opposite-hand helical halves meeting in a chevron. The opposing helix angles cancel the axial thrust a plain helical gear produces, so the shaft needs no thrust bearing — which is why herringbones are a favourite in printed drives. The halves are unioned into one editable part, aligned so the teeth run continuously across the join. Download a print-ready STL or 3MF.
