Khóa số (Combination Lock) 3 chữ số

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.
