I saw this the other day https://makezine.com/projects/make-20/the-unabox/ and decided to try and make one myself. The make article include plans but I decided to rework myself since it was designed for making with hand / power tools not lasers. I had to make a few alterations to the lid as the make version used an angled cut both vertically and horizontally naturally that’s difficult to do with a laser.
I used some proofgrade maple plywood and a few bits of hardware for the hinging element and then a match for the locking pin.
It works fairly well but I’m not totally happy with the bolt for a hinge I might redo it using something like a bit of dowel or some such. The locking pin was also a little small I wrapped it in some tape to make it fit better and I might well replace it. I also might rethink how the lid works to make it lock in better but I’m sort of regarding this as a proof of concept rather than a finished item I’d like to make it with more ornamentation and maybe some nicer wood.
