Vault

A working vault door with multiple combinations. Turn left, then right, and left again to open the lock. 

To assemble, first attach the two pins to the sliding mechanism and insert it into the assembly. Then, attach the switch with the three pins and the lever at the front. Next, mount the wheel with the dial onto the front. Slide the thick axle through the hole, adding a spacer and a disc alternately. Use the small pins to set the code.
