Magnetic Combination Lock Puzzle Box
thingiverse
This storage box uses magnets to shift tumblers in order to allow for the bolt to be retracted and allow the container to be opened. The combination can be decided by the user based on which numbered tumblers are printed. Extra parts needed: 15x 8x3mm Neodymium cylindrical magnets 4x M4x16 countersunk screws 4x M4 brass inserts While printing the buttons, the printer needs to be paused at a specific level to allow for the magnets to be placed and then the print can be resumed. This results in the magnets being wholly embedded into the PLA buttons.
