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.

A two-point spherical Islamic star pattern with nine-pointed and ten-pointed stars. Created using custom-designed software, with a tiny bit of postprocessing in Rhino. Resulting model is lovely and delicate.

By request, a mug-sized version of the Rocket Espresso Cup. Ideal for coffee drinkers despairing of failure to launch, or for pathologically lethargic espresso drinkers. The cup should hold approximately 6-7 fluid ounces.

Please note that I have not fabricated this model yet, so I haven't had an opportunity to evaluate its ergonomics. Your mileage may vary. Conversely, if you order one, please send me a photo!

A small spherical Islamic star pattern with cubical geometry, intended to be fabricated in steel or silver. Wear it as a pendant!

A complex rectilinear design wrapped into a cylindrical band. Could possibly be worn as a (very loose) bracelet, but I'd love to see other novel uses for it.

A simple, geometric menorah based on a clay model I built a couple of years ago. My skill with clay is unimpressive, but the design was easy to recreate as a 3D model. The holes are 3/8" in diameter, which I believe is the correct diameter for Hanukkah candles.

There are twelve distinct ways to glue together five squares along their edges to form a single shape. These shapes are collectively known as the Pentominoes. The Pentominoes are a challenging packing puzzle --- usually, one is asked to pack them into a 6 by 10 rectangle. But they can also pack a 3 by 20 rectangle. I have taken that packing and wrapped it into a cylinder to make a ring. The perfect accessory for combinatorial geometers!

A large version of the Pentomino ring --- a 3 by 20 Pentomino packing wrapped into a cylinder. This design could be worn as a (very loose) bracelet, but I'd be interested to see other novel uses for it.
