Reuleaux Polygon

Create Your Own 2D Shape: A Reuleaux Polygon! Make your own unique 2D shape with constant width, known as a Reuleaux polygon. The customizer allows you to create one with any number of vertices. To build a Reuleaux polygon, draw a regular polygon with an odd number of sides - think triangle, pentagon, heptagon, and so on. Next, replace each side with an arc whose center is the vertex directly opposite the side being swapped out (note that polygons with even numbers of sides don't have an opposite vertex).
With this file you will be able to print Reuleaux Polygon with your 3D printer. Click on the button and save the file on your computer to work, edit or customize your design. You can also find more 3D designs for printers on Reuleaux Polygon.
