This puzzle was originally designed by George W. Hart. I tried to design this in OpenSCAD, which I eventually succeeded in doing. I rounded the edges and corners of the tetrahedron for a better haptic. Thanks to @BikeCyclist the design is now much smoother.

Print twice with support, preferably in different colors.
There are three files with different amounts of backlash.
What fascinates me about this puzzle is that it takes many people a few minutes to solve it, even though it consists of only two pieces, and those two pieces are completely the same.
