The Dual Diogo's Crystal was inspired by Diogo Souza's Hexapod and David Pitcher's Diogo's Crystal Puzzles. This puzzle is a corner turning version because the solid it uses is the Dual of the one underlying the heart of Diogo's Hexapod puzzle. David Pitcher with his Diogo's Crystal, a face turning version, makes the geometry more plainly visible. This model can therefore be considered as the dual of the David Pitcher's puzzle, hence the name chosen, which serves as a tribute to both creators. This puzzle is FDM printed in ABS and then vapor smoothed in acetone. It is very stable and turns smooth. It comes fully assembled and stickered. Have fun!
