As being Sphericons they follow its rules - they roll infinitely on any slanted flat surface. Even more - they are constructed entirely of cones (well almost - except the tips).
The story of it started last June. Being a puzzle designer I love to receive interesting geometrical things, so my wife bought me a birthday gift - an oloid.
An idea of a not perfectly round thing rolling freely got me interested and I found another object of the class - sphericon. Soon its descendants, the Konoids came to life.
The experience of printing a Konoid was very enjoyable - you can see it in gold. I am sure the other materials will have no problem. The only caveat was that I could not print it in ceramic. Can you imagine a ceramic piece of art constantly rolling away? Unfortunately by the rules of the process a ceramic object must have a base to stand on during the finishing operations.
The Konoids don't have that by their definition.
I hope to resolve this with the Shapeways guys soon. They are very nice and responsive.
