Mecanum wheel

thingiverse

RustySpoon1121's design was published first (http://www.thingiverse.com/thing:2318), but my unique, 8-roller, centrally mounted Mecanum wheel uses 624 80034 ball bearings. The necessary parts for assembly include a left or right center wheel ("Felge-links.stl" or "Felge-rechts.stl"), eight holder parts ("Lager.stl"), and sixteen half roller parts ("Rad.stl"). Also required are eight M4x60mm bolts (or eight M4 threaded rods, each 60mm long), eighteen M4 nuts (thirty-two if using threaded rods), thirty-two M4 washers, and eight 624 80034 ball bearings. Finally, an M3 nut and M3 bolt or M3 set screw are needed for completion. For detailed assembly instructions, visit http://pleasantsoftware.com/developer/3d/2010/04/18/the-power-of-vacuum/. Unfortunately, due to an error, 80034 ball bearings were initially used instead of the correct 624. However, a revised design is forthcoming and will be published shortly on Thingiverse (http://www.thingiverse.com/thing:2473). Please check back for updates.
