There are a few models on thingiverse, and one of them comes with some interesting claims: https://www.thingiverse.com/thing:10190 https://www.thingiverse.com/thing:10190 The model's creator says his design was essentially eyeballed because (at least in 2011) there existed no peer reviewed publication describing the actual shape of the Gömböc, making this more of a commercial enterprise than a mathematical discovery. He also appears to have had some dustups with the Gömböc discoverers over his claims who did not appreciate him posting his model. It was not clear to me from the Wikipedia page what the real situation is. Is there currently a published description of the exact shape of a Gömböc? It would indeed be curious if there were not.
