Pragmatic Puzzle Box v2

pinshape

This puzzle box demands a spin to spring open its secrets. A clever mechanism holds the lid in place with four precisely sized 6mm BBs that can easily be embedded during printing or added manually. Give the box a simple spin on a flat surface, and the lid will twist 20 degrees, granting access inside. But locking the box back up is just as straightforward - simply slide the lid into position and give it a turn to secure it in place.
