Mecanum Wheel MK2

This is the second incarnation of my Mecanum wheel design. It's a derivate of http://www.thingiverse.com/thing:2348 which I accidentally designed based on the wrong ball bearings (80034 instead of 624).

This design is now based on the (originally intended) 624 ball bearings. I was able to shrink the whole design, so the center wheel now fits on a standard Makerbot build platform and can be printed in one piece.

See my blog post at http://pleasantsoftware.com/developer/3d/2010/04/23/its-printable for more information on the project. This post also contains a video showing the assembly process.
