Solids Of Constant Width - Variety of 3 shapes

$65.00 $50.00 Sale

Set 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 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.

They did arrive a few days late but I was expecting that with them travelling internationally and everything is moving slower at the moment. They were very well packaged for the long flight and arrived without a scratch.

They are perfectly made and were a great gift to hand over, Thank you!
