I can't resist retrofitting a good used box, and cigar boxes are great!
This locking system is a copy of what was pulled up from a Viking ship! I studied the photo carefully and this is what I came up with. I don't mind sharing these images as the technology belongs to the Vikings, not me, haha.
The challenge was to be able to get the notches in the three dials to work smoothly with the three pins that are mounted to a unified sled of sorts.
Pushing on the button from the outside will require the pins and notches to all be aligned. The more time spent on accuracy makes it more difficult to 'feel' your way to the solution, but not impossible.
Some of the challenges faced when building this puzzle box was the technical aspects of fabrication in general, finding the measurements and right fit is a slow tweaking process that is actually a lot of fun!
Thanks for looking guys!
