Angel/Demon Puzzle

by ecoiras

This Angel/Demon puzzle is my entry for the MakeAnything Puzzle Design Challenge! The puzzle is based on M.C. Escher's "Circle Limit IV" mosaic. In that design angels and demons tesselate the hyperbolic space. I reprojected the motif to planar Euclidean space and extracted the hexagonal tesselating unit. By carefuly splitting the unit tile an angel or demon can then be composed just by reordering the pieces. To complete the model I included a tray to hold the pieces. There is a hole at the back to push the pieces out in case they fit too tight. The gap between the parts is about 0.4mm which should be ok for most printers. Enjoy!
