The Heritombo Cube was actually designed and printed after I started to doubt this design for a Helicotper 3x3x3 would work. After waits for a few missing parts, and a design tweak, it has turned out that I’m revealing the original design after the Heritombo Cube.
I made the cuts shallower first as an experiment, but when I saw the face pattern, I immediately started shooting for a 3x3x3 hybrid. In the event that someone makes a flat cut Helicopter 3x3x3 that doesn’t use shallow cuts, I’ll rename this one.
This was completely designed on a flight to China, and even uploaded to Shapeways somewhere over the Pacific.
This is now on Shapeways for $85.

This is another series I was bound to complete. It is the Brachio Star– the icosahedral version of the Dino Star. Since it’s bigger than the Dino Star and bigger than the Bronto Star, the name “Brachio Star” sounded good.
Since I got to design the whole thing, it moves nicely and is stable, if a little stiff.
This is now on Shapeways for about $150 in wsf HERE. You need to order all 3 sub models.
