Solids Of Constant Width - Triangle - Set of 3 Phone Stand We machine them from AircraftSet of three Cones of constant width. This model is based on a Triangle. CNC machined in Canada out of brass or aluminum bar stock. Approximately 1" in diameter. These are machine finished and light hand polishing is done. 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
