Classic Orbiform - a Reuleaux - Free 3D Print

A (3D) orbiform is a mathematically perfect solid of constant width. Its profile is based on the Reuleaux triangle (a constant width curve based on an equilateral triangle) 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? Check out the other models in the collection: Pentagonal Orbiform…
