Summary
This was a project that I have been working on for a few months on an off. The wheels are a little larger than 2 inches ind diameter. The are designed to be used on the Tamiya 3mm shaft gearboxes.
These where the ones that where featured on the Make: website.

There are two versions of the .STL The one that ended in inches is the one I used for the 3d-print. The other one should be in millimeters. For some reason the file size is different.
The .STl files are large. Download the zip file not the .STL
Instructions
Print using a commercial Printer such as a Dimension SST. Assemble using a 3/32 brass rod or tube.

If you are printing the wheels with the rollers already in place, why are you using brass tubes to hold them together? Why not print print the whole thing? I do have a 3D printer (like most people on thingiverse I would think) so I know their limitations.
I think I might print a couple for my rolling backpack. Anyone know if it's MakerBottable?
I am not so sure about this one. There are a few mecanum wheels on this site that look possible.
Nice!
I think it might need tires to work properly though.
How about heat shrink tubing? (If the thickening of the tube at the narrow ends of the rollers is a problem, they could just be narrowed a bit more)
I had coated a wheel in the Liquid Tape used for electronics. That was a huge improvement. I just never left it on because I decided to dye the rollers.
