Skate Wheel 80mm

Model of a commercially-sold 80 mm diameter inline skate wheel that I happened to have. The actual uncompressed OD of the wheel is 82 mm. I plan to use this as a drive wheel on a robot and needed this model to make a driver pulley that would interlock with the spoke holes in the wheel ([this one](http://www.thingiverse.com/thing:567481)). This model isn't fully detailed, just has the dimensions that mattered in my case. OpenSCAD file included.

EDIT: I was surprised to see some people have added this to their "things to make" list... just realize that photo is of the commercial molded wheel, not a 3D print. I only modelled this to make an interlocking part.
