Two-Piece Locking Puzzle

thingiverse

A fascinating challenge indeed! The goal is clear: to dissect the puzzle components separately. Even with prior knowledge of what's inside, it may still pose a slight test of skill. # Printing and Assembly ## Prepare To get started, you'll need the following materials: 4 metal balls approximately 9mm in diameter (slightly smaller alternatives will work too) 4 pieces of metal rod with a diameter of 4mm (I used brass rod), each about 28-30mm long Round off the ends of the rods using sandpaper. This can be achieved by chucking them into a lathe or an electric drill. ## Printing Pause printing at the 19mm layer height and insert the balls and rods into their designated spaces (balls in round open holes, rods in the slot joining ball holes, two in each puzzle half). Resume printing. ## Attention If you print through to completion, it will be impossible to assemble the puzzle. If your printer cannot stop mid-print, split the puzzle at around 18mm layer height and glue the components together after printing.
