New challenge!

Sphericons are mathematical toys that roll on a plane in a funny way. Let's try to build a simple sphericon - hexacon.

Its name is derived from the word hexagon implying the hexagonal shape of its middle cross section. Like other sphericons , with cross section edges number that has an odd factor, while rolling on a plane, its maximum height remains constant. The hexaconâ€™s surface circumscribes a **regular octahedron.**

The challenge is to build solid 3d model of hexacon with as less as possible features (I used 5 features).

If you need hints, this video will help you.

I also ask you to share your opinion on how to make hexacon from metal (not necessarily solid).
