"The Brain" Puzzle
thingiverse
"In the Lost City of Atlantis, many millennia ago, an advanced civilization flourished. Mentioned in the writings of Herodotus, was an ancient machine so intricate that it sounded amazingly like a computer. It is rumored to be the inspiration for the Gray Binary System, the basis for “The Brain”. There is only one solution which requires 170 sequential moves. Can you channel the knowledge of Atlantis to solve the puzzle?" My son and I worked on this together. I printed this with 50% infill. Make the sides somewhat thick because there is some stress on the nut and bolt at the top. http://www.magnif.com/shop/the-brain-puzzle/
