A Reuleaux polygon is a 2D shape of constant width. Use the customizer to create a Reuleaux polygon of any number of vertices! To construct a Reuleaux polygon, draw a regular polygon with an odd number of vertices (triangle, pentagon, heptagon, etc.). Then, each side is replaced by an arc who's center is the vertex opposite the side being replaced (notice that the sides of a polygon with an even number of sides does not have an opposite vertex).Customize the number of vertices, width, and thickness of the Reuleaux polygon. Then chose whether you would like to engrave the top or bottom face with the number of vertices, and customize depth and size of the engraved features.
