The first Reuleaux Minx is made by Traiphum. It was a truncation only mod, his version 2 involved extension to be more "Reuleaux", but I prefer the relatively uniform pieces' sizes of the V1. So I went ahead and made myself one. This is my first pillowed mod, and I'm pretty satisfied with how it came out. It is the most elegant looking puzzle I made! One thing though, it is not really a Reuleaux tetrahedron. A Reuleaux tetrahedron is attained from the intersection of four spheres which are defined: their origins placed at the vertices of the regular tetrahedron with the radius equal to the edge length of the tetrahedron. My puzzle is more pillowed than that due to the amount of truncation I cam make on a megaminx. So, the origins of the spheres(roughly) would form a smaller tetrahedron within the regular tetrahedron. So if any one knows the name of this type of shape, please tell me, I'll change the name accordingly.
Here are the pictures:

This is showing the edge, I made it as straight as I can

Cool. One of my favourite Megaminx shape mods. I think it should have those small stickers though, the puzzle just doesn't look complete without them.

Yeah, I liked those small stickers too, but the amount of inset needed for stickers leaves no room for them.

Of all the mods I see on TP, I most admire the "curvy" ones. A great mix of precise engineering and artistic skill. Beautiful.

I agree rename with the news appropriate name, cuz my is not complete Reuleaux shape.
tetrahedral puzzles is the most my favorite shape, and cuboid.

Nice done.

Very nice. The pyramid scheme is my favorite megaminx mod, and this is a very nice build.
