Super Secure Combo Locks

These are 3 of my combination locks, varying from small to insanely large. The first one (smallest) has 10 buttons as inputs and 4 digits in the combination for a total of 10,000 possible combinations. The second one (middle size) has 14 buttons as inputs and 6 digits in the combination for a total of 7,529,536 possible combinations. The third one (largest) has 15 buttons as inputs and 8 digits in the combination for a total of 2,562,890,625 combinations. If you like these please favorite, diamond and subscribe :).

To change the combinations on any of these, simply move the torches on the bottom of the machine to line up with a button, and use the signs on the side to find out which digit each torch represents.
