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 needed this model to make a drive gear (pulley) that would interlock with the spoke holes in the wheel (https://www.youmagine.com/designs/gt2-pulley-for-skate-wheel). It isn't fully detailed, just has the dimensions that mattered in my case. OpenSCAD file included.
