3d printable pulley centering jig for centering a large drive pulley on the wheel for the lacroix boards electric skateboard.

note this thing is just a disc with a hole in it. so I knocked it out with openscad and made it customizable. should be useful for anything else that needs a disc with a hole in it.

UPDATE: added spoked versions on the chance that they save someone plastic.
