If anyone can find a cad model, I'll machine one out of aluminum or print an SLA.

  Would be OK for personal use, but for commercial production it looks like they've put a variety of legal protections on the shape/design of it: http://www.gomboc-shop.com/app/urwfilter/license/do/action/ShowForm/index.html http://www.gomboc-shop.com/app/urwfilter/license/do/action/S... So much for not being able to patent math.

    How fault tolerant are they? What if I made one to within 100 microns - I imagine it would still self-balance itself pretty well, and that specific shape would probably not be covered.

    From http://www.gomboc-shop.com/app/urwfilter/faq/do/index.html http://www.gomboc-shop.com/app/urwfilter/faq/do/index.html Is there only one Gömböc shape? No, in fact, there are infinitely many Gömböc shapes. However, the overwhelming majority of these shapes could never be manufactured because these shapes are much too close to the sphere. Currently we manufacture two different shapes ( 8005 and 8205 ). Both are quite similar and have a substantial deviation from the sphere. They could potentially get a design patent on each of the specific shapes they make and certainly on their name, but good luck on anything beyond that.
