Parametric Meissner tetrahedron
thingiverse
This is an openScad script to generate your own solids of constant height. Instructions Just choose the desired height on the first parameter (size), then comment/uncomment the module calls to generate either the full piece, or one of the two halves to print. I tried printing it in one piece (without support) but failed miserably, so I strongly recommend you to print the two parts and then blue them together. Printed with PLA at 200C, 0.3mm layer height worked pretty well for me. Please note that for some obscure reason, the slit opening in the top part printed smaller than the slit opening in the lower part, so I couln't fit the slit in. Glued well without it anyway.
