Parametric Spur Gear

A parametric spur gear, made with the involute curve tangent line [approximation](https://nptel.ac.in/courses/116102012/40), as Fusion 360 doesn't support equation driven curves (yet). Module, number of teeth, height, hole diameter, and pressure angle are adjustable parameters. See the [parametric gear toy](https://www.thingiverse.com/thing:3336663) for a test model using these gears.
