Meissner bodies of constant width
thingiverse
Against all instincts, a sphere is not the only geometric shape that has a constant diameter. There are an infinite amount of others, of which the Meissner Tetrahedron is the coolest. This set contains 4 shapes, each different, but with the same constant width of 35mm: Meissner Tetrahedron Revolved Reuleaux Triangle Revolved Reuleaux Pentagon Revolved Reuleaux Heptagon I know this isn't the first collection on Thingiverse, but I CAD'ed them myself, hence no credits to others. Well, okay, credits to Reuleaux and Meissner! Watch them do their thing on http://youtu.be/_8Fe-OLr42Y If you make them, please share the picture! Instructions I had to sand away some support, as well as little blobs on the top. However, it should be possible to print with barely any support, and therefore (almost) no sanding.
