Rubik’s cubes are a popular puzzle — one found exciting or infuriating depending on your personal bent. [PuzzLEGO] has designed a LEGO Rubik’s cube, with the latest revision improving on flimsy earlier designs.
The first step was to design a core that would allow the cube to rotate freely without being too loose. This involved a lot of trial and error until [PuzzLEGO] found just the right combination of parts to do the job. From there, it was a matter of introducing the edge pieces and corner pieces without jamming everything up.
It took some experimenting to get everything moving together smoothly, but the end result is pretty impressive. It’s certainly not a build you’d use for speedcubing; the fragility meant that it took 20 minutes to solve just one face. [PuzzLEGO] hopes to make further improvements to increase playability.
If you want to replicate the feat, you’ll need plenty of little Lego bits and pieces, but it’s definitely a replicable build. Alternatively, consider using Lego to build a Rubik’s Solver, instead. Video after the break.
