2x2 Chain

The puzzle that caught my eye recently was featured in one of my Print It Yourself videos: https://www.youtube.com/watch?v=ePinNtag72c. This 2x2 Chain is a challenging twisty puzzle that combines three standard 2x2 Rubik's Cube puzzles into an exciting problem to solve. While the outer two 2x2 cubes solve like regular ones, the inner 2x2 cube faces significant external constraints, making its solution incredibly difficult. I highly recommend creating this puzzle for yourself because it's extremely easy to make. If you have three 24mm 2x2s on hand, simply print out two bars and twenty extensions, then attach them as needed using glue. You can arrange the bars however suits your design, but for inspiration, check out how I positioned mine in my linked video above.
