I love this! Make sure you get magnet polarity correct, I had one backwards and it wasnt strong enough to hold the lid without everything falling out. correct polarity and it stays together under its own weight.

I printed everything in pla, bumped walls up to make the 'pin' part 100% I fill. Hammer the pin in with a soft blow mallet against something firm like a tile floor. My desk was absorbing enough impact to keep it from fully seating.
