This is a card box I designed for laser cutting, this is the mark 2 version of the big card box.
Added a latch.
Sized for card games, business cards, or small quantities of important items like nuts, bolts, and drugs.
The latch is a little finicky... I think the teeth need sanded to sharpened leading edges. Must test later.
Strong enough to stand on, and the joints have a ton of torsion and tensile strength thanks to the hook tab joinery I came up with. Will have to think of a good way to demonstrate the joinery strength separately... Maybe a test until failure mechanism... Someday
