Ultimaker Core Lessons: STEAM lesson 5—Sphericons
When you rotate a symmetric polygon around a mirror axis, cut the solid into two equal parts, and then put the parts back together differently, you produce a sphericon, a three-dimensional solid with one side and two edges.
Why does it work? Create sphericons to explore the relationship between cones, cubes, and octahedrons and find out.
