Solids Of Constant Width - Variety of 3 shapes Material:Brass The 2 that I useSet of three Cones of constant width with one of each Triangle, Hexagon and a Heptagon. CNC machined in Canada out of brass or aluminum bar stock. Approximately 1" in diameter. These are non spherical solids that amazingly have constant width in every directionallowing them to roll smoothly. They are derived from two dimensional curves that were put into use by the 19th century German engineer Franz Reuleaux.
