Meissner bodies of constant width

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 oth
