Print in mm for correct size. I discovered these shapes some time ago through Numberphile: https://www.youtube.com/watch?v=cUCSSJwO3GU Next, I decided to create my own shapes of constant width (I made them back in early 2014, then recently found them in one of my folders and thought I would upload them with a nice rendering), specifically the:\n2D Shape – Reuleaux Triangle\nand the\n3D Solid – Revolved Reuleaux Triangle\nTo learn more about them, check out https://en.wikipedia.org/wiki/Reuleaux_triangle I also wanted to mention Mitra Smit who created “Meissner bodies of constant width” which I printed some time back and they’re quite impressive: http://www.thingiverse.com/thing:649488
