Sloppy Soma is a variation of the classic Soma Cube puzzle by Piet Hein from 1933. This version has the cutting planes at an 88-degrees angle, instead of 90. This makes the puzzle look sloppy. It also makes the puzzle harder to solve, as it is never clear whether two pieces fit together.The puzzle took 11 hours to 3D print on a Dutchy 3D printer. 36 meter of 1.75-mm PLA filament was used to print it. The puzzle weighs 108 grams.
