Half Proportional 2x2x4 v2

thingiverse

This is the second version of my enhanced 2x2x4 cube, with several key modifications that make building and completing it significantly easier. Check out the original here: https://www.thingiverse.com/thing:2474612 To print this design: You'll need one core piece, eight inner corner pieces, eight outer corner pieces, nine inner edge pieces, three inner center pieces, and three bandaged inner center pieces. Assembly requires six M3 screws and three springs. Cut each spring in half, then place a half-spring on either side of the puzzle.
