Product Description
This is a model of Boy's Surface, a one-sided surface with no edges and no pinch points.

In the cutaway images you can see a small ball. It can roll in three directions but is trapped in the space cut out by the single-sided surface.

The ball is visible through a single cut that winds around the surface.

Note: The ball is red for clarity in the screenshots only. The entire model will be the same color when printed.
