Real BELT SCAD modules

I needed a belt module to do the inverse so I can clamp a belt in an object, I wanted a real inverse not like most of the design out there where its basically just square.

Right now its support Gt2 belt but can support any round belt, if you know the dimensions, you can add new functions easily.

Supported Modules:

belt(width, length, pitch, height, teeth_height, radius)
inverse_belt(width, length, pitch, height, teeth_height, radius)

gt2_belt(width, length)
inverse_gt2_belt(width, length)
