WAS: NOT YET for sale. I'll test it first.
NOW: tested, works ok. You also need some kind of inserts (unless you want these to be on your bookshelf only ;-) Hasty ones can order now. However, later I'll check if I can make a full set cheaper than one-by-one. You need 2 of these to get front wheels and 2 of the back wheels.

Not: I cannot guarantee the durability of the material; Shapeways restrictions should be applied. So if you drive with these rims, do it at your own risk. I'm personally quite confident on the durability, but cannot be liable for possible accidents or faults.
