Set 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 direction—allowing them to roll smoothly. They are derived from two-dimensional curves that were put into use by the 19th-century German engineer Franz Reuleaux.
