Tetromino like Cube Puzzle, Soma Cube pieces

thingiverse

All seven pieces (six are tetrominos) that can be combined 240 ways to form a cube. Invented by Piet Hein in 1933. There are many other patterns that can be built, using all seven pieces. Here's a link to forty patterns, with solutions also: https://www.fam-bundgaard.dk/SOMA/SOMA1/SOMAFIG1.HTM. Two of the pieces need supports (should be obvious which ones). The rest do not. The individual cubes are sized at a grandiose 30mm x 30mm x 30mm, for detail; I recommend uniformly scaling all the pieces a little smaller. My initial print was at 50%. But you do you. (You can also try out the puzzle virtually at http://somacube.org/.)
