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 hexacon’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).
