Parametric Involute Gear for Fusion 360

This is an equation driven metric gear with pretty good involute teeth.
Click on the "Change Parameters" tool in Fusion and edit the number of teeth, module, and face width to generate different gears.

The model may be a bit fragile, particularly with big jumps in size. I have not really vetted this fully. Background: I first made a parametric involute gear with equation-driven curves in Pro/E in the mid 90's, then another one for Solidworks in the 2000's, and a couple of years ago I decided to try making one in Fusion. Let me know if you have ever made one yourself, or have seen one elsewhere. I would be curious how it was done.
