Solids Of Constant Width - Large Triangle - Set of 3
Set of three Cones of constant width. This model is the large size.
CNC machined in Canada out of brass or aluminum bar stock. Approximately 1.75" 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.
