PolyGear OpenSCAD Gear Library

I will try to keep the archive on Thingiverse updated, anyway you can browse and download the most recent version here:

#Introducing PolyGear#


PolyGear is a powerful OpenSCAD library to create **spur** and **bevel gears** as a single polyhedron. The library allows full control of the **involute tooth profile**, including pressure angle, backlash, variable helix angle, addendum, dedendum and profile shifting.

Being able to vary the helix angle allows for instantaneous generation and switch between herringbone, zerol, spiral and customized profiles; all constructed as a single and smooth polyhedron even for small facet number.

The gear is constructed in an **extremely efficient** way, by triangulating a minimalist vertex cloud with a single polyhedron.

I wrote this library because I was unsatisfied with the existing ones:
