This is a bit of a work in progress, and I'd love to hear input from someone. This is a puzzle of sorts; you must assemble the pieces into a dodecahedron. The pieces themselves come from dissecting the dodecahedron in a somewhat funny way. I say it's a work in progress because I feel like the puzzle could assemble and hold together better than it currently does perhaps with some clever tweaks.
PRINTING: you must print 3 copies of each of the four STL files, for a total of 12 pieces. It's worth noting that piece_3 and piece_4 are the mirror image of piece_1 and piece_2, respectively. The pieces shouldn't require much precision or infill. They will require some support.
---UPDATE 27 Jan 2019---
I remade this puzzle, with a slightly different value of a parameter (the amount of "twist", essentially), and I think the puzzle improved. It holds itself together better, yet is still assemblable (too much twist and it cannot be assembled!). The piece files reflect this new geometry.
