Pragmatic Puzzle Box v2

This is a puzzle box that requires a spin to unlock. The mechanism that locks the lid in place is itself locked by four 6mm BBs, which can be printed in place, or placed during the print.

A simple spin on a reasonably level surface allows the lid to be twisted 20 degrees, which allows the lid to be removed. However, closing and locking the box does not require any tricks; simply insert the lid and twist it to lock.
