We've been talking about the tweel for a long time but check out this article and video about what Michelin has taken the concept to new heights:

Interesting concept.

The last I heard was that 3D printing was really expensive but maybe they can get the price down to a reasonable amount.

Not just for atv or car parts,but I hope there's also a future for it in medicine,prosthetics,etc. Don't know what the cost was,I'm sure it was expensive, but it sure helped this dog have a better life.
