Cross Box Puzzle
About a week ago I made this puzzle box as a prop for a LRP event, I've kept it back just in case someone saw it in advance. It's a great little build and a good puzzle, I won't expand on the details yet because I may be working with the creator to make more puzzle boxes via kickstarter but in the meantime you can get an idea of it from this video (and that's enough breadcrumbs if you really want to know more).
