About this 3D model

I designed a 9mm bullet box which holds 50 rounds. The top slides on and is hold by grooves in 5 positions. That way it locks in place to reveal 10 bullets at a time. Easiest way to open it is by pushing in the middle of the lid, because that way, the “locking pins” disengage. This is the version vor 9mm Para. I also have a version for 9mm blanks P.A.K
