Fast Parametric Involute Spur Gears
thingiverse
A parametric spur gear library built with OpenSCAD list comprehension creates polygons at incredible speed, reducing compile and render times significantly. The library provides functions to calculate the pitch radius for your gears, ensuring they mesh properly within your design as seen in the gear test example. Designed to be straightforward, it generates 2D templates of gears and racks, giving you complete freedom to use them as desired. Update: April 4, 2017 - Dedendum calculation error fixed, thanks to JPeterG's help.
