Hanayama Cube Puzzle

pinshape

The puzzle wasn't my idea - I just stumbled upon it and managed to print it on my UM. The challenge is to create a unique square or cube from four identical pieces. It's a tricky puzzle, but once you grasp the solution, it's not that difficult to achieve. If you succeed, you can even attempt to push yourself further by trying to get two connected rings as shown in the pics above. To tackle this puzzle, print the part four times. The parts were printed upright with a small support holding one side (I've included a picture of a part with support). The printing settings are as follows: * Layers: 0 and 2mm * Shell: 0.8mm * Infill: 25% * Speed: 50mm/s * Approximate Time: around 30 minutes per piece * Weight: approximately 7 grams per piece Considering the infill percentage, it might be beneficial to increase it slightly to prevent parts from breaking when someone gets frustrated trying to solve it.
