> Each Gömböc comes with a booklet containing every necessary information about the product, as well as a unique product ID to identify the Gömböc and prove its authenticity. Sandblasted Al: 239 Euro Porcelain: 606 Euro Steel: 499 Euro Bronze: 599 Euro Plexiglass: 199 Euro Polished Al: 269 Euro Al (rough polish): 199 Euro Black (polyoxymethylene): 249 Euro https://www.google.com/search?q=gomboc+3d+model https://www.google.com/search?q=gomboc+3d+model I'm guessing it costs an order of magnitude less than those published prices to machine an aluminum one, given an accurate model? The product page says the Al one is 500g, so the machining cost is probably the most significant factor?

Strange, I was looking for gömböcs this morning (like 12 hours ago) and now I find them in the HN front page. I found this website which has much cheaper gömböcs (42 €): http://gomboc-online.com/index.php/gomboc.html http://gomboc-online.com/index.php/gomboc.html But apparently their only shipping method that ships outside Hungary is "currently unavailable". Well, there is also the option "SZEMÉLYES ÁTVÉTEL GLS CSOMAGPONTON" but Google is not very concrete when translating it. It sounds to me like picking up in a "something-point" though, which also looks like it's not international shipping. If anyone keeps investigating and finds a gömböc that wouldn't make me broke and can ship without shenanigans outside of Hungary, I'd be grateful.

  > SZEMÉLYES ÁTVÉTEL GLS CSOMAGPONTON Means that you can pick it up personally at a GLS (like FedEx) point. The checkout page does say it ships internationally: "DHL EXPRESS WORLDWIDE"

    OK, I now see that the problem is that for some reason they do not ship to my work address's postcode... if I enter that code, they say that DHL delivery is temporarily unavailable. With my home address postcode, it works (a pity I'm almost never home).

      Maybe ship to friend / family address? Just an idea.

> The shape of those bodies is very sensitive to small variation, outside which it is no longer mono-monostatic. For example, the first solution of Domokos and Várkonyi closely resembled a sphere, with a shape deviation of only 10−5. It was dismissed, as it was extremely hard to test experimentally. Their published solution was less sensitive; yet it has a shape tolerance of 10−3, that is 0.1 mm for a 10 cm size.
