Enneagonal Orbiform - Free 3D Print

Enneagonal Orbiform is a mathematically perfect solid of constant width. Its profile is based on the regular nonagon (9-sided polygon). It’s one of the rolling solids - an interesting geometrical form that rolls like a sphere despite of not looking like it would be able to. The secret behind the rolling is the equal distance behind between the points and their opposite vertices. Like the idea?
