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). 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.
