3D model description

Simple working and robust lock designed for a wooden toy treasure chest. The key I used was based on the key found in this thing although any key will work even a screwdriver would do. Its not meant to be a secure lock. The lock is made simple because thin complex 3D printed parts break easily and kids lose keys.

The treasure chest I built, uses these hinges

and uses these box corners


A hole is cut into the box lid then the lock mechanism is placed together and screwed to the underside of the lid before cutting a grove with a Dremel type rotary tool into the inside of the box as a latch for the barrel disc.

If you found this useful, please donate what you think it is worth to my Help cover the time of design.
Thanks, Enjoy!
