Miss Melody diary code lock

thingiverse

This is the lock component of my daughter's diary lock - the very part responsible for keeping her deepest secrets safe from prying eyes. Crafted with precision using PLA material, this numerical keyboard lock boasts an impressive level of security. To install it properly, you will need a 3mm screw, along with a washer and a matching 3mm nut featuring a 6mm head. The key to getting the nut stuck firmly in place lies in applying heat - simply use a lighter to warm it up before pressing it into the cylinder. As the metal cools down, it will seal itself inside, making any attempt to remove it virtually impossible.
