Puzzle maker Coren Puzzles has created a 22×22 panel Rubik’s cube with 200mm edges. The project took eight months and features 2,691 working parts created using a Prusa i3 3D printer. Although the cube is a working puzzle, a demonstration video shows it being manipulated with a great degree of difficulty.
