Rover Wheel

This is a somewhat simple wheel designed to be directly attached to a motor. It looks vaguely like the *Rover Mars Explorer* wheel. I am also working on a mould so you can mould a rubber tyre to the wheel or as it stands you can cover it in a thin layer of [sugru](http://www.sugru.com). It should also work as-is, particularly on carpet or rough surfaces.

The OpenSCAD file has a range of tunable parameters so feel free to tweak and experiment.
