Hanayama Cube Puzzle

thingiverse

I just stumbled upon this puzzle and somehow managed to print it out on my UM without any prior knowledge of its existence. The goal here is to create a single unique square or cube using the four identical pieces provided. Don't let its complexity fool you - once you grasp the solution, it's actually quite straightforward. If you're up for the challenge, try taking it to the next level by creating two connected rings as shown in the pictures above. Go ahead and give it a shot!
