An espresso cup specially designed with fins, to ensure the successful deployment of your rocket fuel. All systems are go! Paraboloid bowl holds approximately 1.5 fl oz. or 45 mL. (Note that I previously claimed the cup held 60 mL. While my 3D modelling software still reports that as the internal volume, some combination of the printing process and glazing is robbing me of internal volume. Contact me if you'd be interested in a larger, more expensive 60 mL cup.)
After receiving feedback from Shapeways, I've created a slightly revised model for the cup. I'm told that this model will be easier to print and glaze, leading to a more reliable product. The changes are minor -- it's a little wider, a little heavier, and has more rounding on edges that were previously sharp (a 3D rendering shows the differences above).
Update (April 13th, 2013): The cup has had a great run on Shapeways, and I deeply appreciate the attention and positive feedback it has received. The bad news is that I've got to stop offering it for sale here. The good news is that the cup is now available commercially! It's being manufactured by Fred and Friends, sold under the name "Blast Off! Espresso Cup Set". It's already available for purchase online (perpetualkid.com, thinkgeek.com), and I'm sure you'll be able to find it in your favourite housewares store soon.
The scarab is in a typical defensive posture, legs folded. As a result, it presents a strikingly different aspect when turned over.
This model is scaled to fit well in the hand, and because of the folded posture, is robust enough to travel well in a pocket. Mine goes with me everywhere. Warning: the claws are as sharp as they look.
NOTE: This is just one half of the ring. - You must order 2 to have all the parts to make a whole ring.

This die is inspired by the repulsion force polyhedra. Nonetheless, the underlying polyhedron (not rounded) is very different from the shape that can be obtained through this technique with 11 points repulsing each others.
Actually, I calculated the positions of 11 points to have a maximal radius for the circles resulting from the intersection of this underlying polyhedron with a sphere with the following constraints:
- 2 poles (upper and lower face - parallel to the horizontal plane)
- 3 points around each pole
- 3 remaining points corresponding to 3 faces perpendicular to the horizontal plane
The result is a truncated sphere with 11 circular faces of same radius.
It is numbered from 1 to 11: 2 numbers are on faces (poles), 6 between vertices and face and 3 on edges. The sum of the numbers on the 3 upper vertices surronding the North pole is 18. Same thing for the sum of the 3 numbers on the lower vertices surronding the South pole and the sum of the 3 numbers on the edges of the equator.
This die is made of a shell of 1.5mm that contains support material to make it heavier. The engraved numbers have a 0.75 mm depth. They are quite big since they overlap the surrounding faces and thus should be very easy to read.
