Four Mirror One puzzle by Osanori Yamamoto

thingiverse

This is an enjoyable, challenging puzzle! It's designed by Osanori Yamamoto, a renowned Japanese inventor who also created the Bisect Cube featured on Thingiverse. His puzzles are not just clever, but they're also ideal for 3D printing as they require no support structures. The puzzle consists of one ring-shaped piece and four identical T pieces. To solve it, arrange the Ts in a mirrored pairing as shown in the photo. You can find the design on Puzzle Will be Played website at http://www.puzzlewillbeplayed.com/643Ring/FourMirrorOne/. I've prepared STL files with a small bevel to avoid snags during movement and a 0.1 mm offset for smooth movement. Each unit cube is 8mm, but feel free to scale it up or down. Note that fit may loosen as the puzzle size increases or tighten for smaller copies. Print one ring piece (S1) in one color and four T pieces (S2) in another. I suggest a medium infill and 0.2mm layer height for a nice top surface. Have fun!
