Designed on Christmas Day 2012, here is the second of my series of printable interlocking puzzles, and this time it's a 4x4x4 cube.
'Printable' means... no support material required.
'Interlocking' means the puzzle pieces fit together only in the correct sequence and will not fall apart when the puzzle is moved.
I have uploaded the six pieces individually to allow each piece to be printed a different colour, but have also provided an STL file with all six piec...es arranged together for convenience. If you want to print the puzzle in PLA you will need a fan to prevent the tallest piece from melting. You will need a well tuned printer to ensure that you get a nice snug fit when you assemble the puzzle. I used Slic3r with settings of 0.2 mm layer height, 0.4 mm extrusion width and 40% infill at 30 mm/s.
