A Reuleaux tetrahedron is a three-dimensional body of constant width, just as a sphere. In order to make the object hollow one of the sides has a small hole.

The objects in the photos are made of White strong and flexible. They are light but sturdy. Suitable for experiments, testing practical math or just playing around. They are pretty awesome.

The model is now updated with a slightly larger hole. This makes it easier to empty the object of excess material.
