Impossible Dovetail Puzzlebox Improved

thingiverse

I took one of the solutions to the dovetail puzzlebox by jphnny4 and made some significant improvements. Given its compact size (less than 2 inches square), think about scaling it up if you prefer a larger version. * A central hole is designed for hiding an item * Matching holes are incorporated to add a magnetic ball lock feature * The top and bottom decorations were removed, as I didn't find them appealing These pieces will easily print without support, with the flat side facing down. Be sure to sand the inner sides and edges of the puzzle before assembly, as it prints very snugly and sharply. For the magnet ball lock, assuming you don't scale the puzzle, superglue or epoxy a 3 mm diameter magnet into the matching hole on the shallower side. I used two smaller magnets to create a more secure catch, but this isn't crucial. On the opposite side with the deeper hole, a 1/8 inch diameter steel ball bearing was utilized. Before locking, test fit and ensure the puzzle is smooth and the ball can move freely through the hole. Then, simply assemble and turn it over; the ball should connect to the magnet and lock the puzzle in place. Now the solution involves tapping the puzzle to dislodge the ball/magnet lock and then pulling the pieces apart. * I apologize for switching between metric and imperial units, as that's how magnets and ball bearings are typically sized when purchased on Amazon
