Spheroform with true Tetrahedral Symmetry

This is a solid of constant width. Same principle as https://youtu.be/270qEZKXAfQ?t=153
But this shape looks like a fat pyramid instead of an acorn. Also it was more challenging to CAD :)

The STEP and Solidworks files has all the bodies that was used to create it so you can see how it was cadded.

Please note that this isn't a Reuleaux tetrahedron (not a solid of constant width) nor a Meissner Tetrahedra (not full tetrahedral symmetry) but something slightly cooler :)
