This is a basic redesign of a lock that I saw a couple of years ago. It is fully functioning and works like a real lock. To add, when you open the lock the combination is automatically mixed up and doesn't show the correct code. It can easily be set to whatever 3-digit combination you prefer. The only non-printed part is an M3-20 screw and a locking nut. While this lock is not exactly secure, it's still a neat proof of concept.
Parts Needed:
-M3-25 Screw
-M3 Nut
The only part that requires support is the Lock Hook V2 which I have included a print file for.
The author marked this model as their own original creation.
