Reuleaux Triangle Rollers

3D printed in white nylon plastic with a matte finish and slight grainy feel.
Product Description
Set of four Reuleaux triangles that can be used as free wheels or rollers for math classroom demonstrations.  Each wheel is hollow and about 1 cm thick and 3 cm in diameter. They are looped on a thin ring that can be cut away and discarded.

Reuleaux triangles are curves of constant width.  Set the four rollers on a flat surface and line them up like the wheels of a car.  Then place a large flat book on top of them.  Roll the book over the rollers and notice that the book stays at a constant height, just as if it were rolling on a set of four cylindrical wheels.
