Apparently Impossible Cube
thingiverse
Iwahiro's Apparently Impossible Cube is a coordinated motion puzzle, requiring all pieces to be simultaneously positioned correctly. Obtain the original from puzzlewillbeplayed.com/444/IwahiroAIC/1/. To print, produce two of each part at high resolution; I suggest a 0.2 mm layer height from a 0.3 mm nozzle. The pieces have been designed with edges featuring slight bevels and offsets for a snug fit, although this may vary depending on your printer. Watch the puzzle in action, along with its solution, on YouTube at http://www.youtube.com/watch?v=1J8fA3t3Y78 if you dare not to try solving it yourself.
