A Megaminx transformed into a Tetrahedron! This design requires no screws; the centers snap into the core.
Snap all 12 centers into the core first, then assemble like you would a normal Megaminx. Glue is needed to attach the pegs to the center caps; the tolerances were made to fit tightly fresh off my printer, I cannot guarantee that the fit will be perfect when you print it on your own machine.
This puzzle was designed entirely in OnShape. A sticker template is included in case you have your own vinyl cutter.

All the parts should be printed mechanism facing down. There is an alignment hole on the bottom of each piece, so that you can reference the inside surface to "lay flat" if your slicer supports that.
