Re-Keyable Cylinder Lock

This simple key lock can be re-keyed to create 256 different key/lock combinations. It's an interesting example of how locks work and maybe even useful to incorporate into your own projects. This is a great project for those with good eyesight and steady hands.The lock uses 4 sets of pins, where the overall length of each set of pins is the same, but where the individual pin lengths vary. And there are also 4 different length key pins that go into the key, with a particular length key pin matched to the lengths of the pins in the lock. You'll also need a single thin rubber band to act as the bias spring for all 4 sets of pins.Print SettingsPrinter:UDIOResolution: 0.2mmInfill:15% Notes: Print 1 each of the parts Lock1, Lock2, Lock3 and Key.
