Parametric Mecanum Wheel Generator Tool

This is a tool to generate Mecanum wheels for a wide variety of possible sizes and shapes using OpenSCAD. I'm not sure how to set up the Thingiverse customizer for multiple files, so the easiest way to get started is to download the three SCAD files and change parameters in the wheel parameters file and watch the resulting shapes change in the hub file.

It attempts to create roller shapes so that when the wheel is spinning, the contact surface matches the three-dimensional shape of an arbitrary "virtual wheel" that is formed by rotating a cross-sectional shape around the axle. Slides explaining that idea are included above.

Two objects are generated: a hub shape that holds the rollers and fits onto a keyed motor shaft, and the shape of a single wheel spoke roller piece (1/2 of a roller) for a mecanum wheel.

The roller pieces is created by taking the intersection of a cylinder defining the possible volume of the roller, and intersecting it with the virtual wheel shape. A sli
