Customizable Reuleaux Polygon

A Reuleaux polygon has a constant width, just like a circle. It is my first try with customizer, so I just did it as an experiment. It currently supports Triangles, Pentagons, Heptagons, and Nonagons. WARNING, if you print a Triangle and a Pentagon with the same distance between vertices, they will NOT work together. This will be added next. The picture above was made with MakerBot Mini.
