I wanted to find a good test for Bambu Labs new Wood PLA.  I searched for a good treasure box, and found this one on GitHub by DrLex0.

Its quick printing and the locking mechanism works great for kids (locks, but still easy to open without a key).  
It also looks and feels FANTASTIC using wood PLA. 

Make sure visit the designer's GitHub page for full instructions and a smaller version.
