M23 Armament subsytem (Blain Predator)

A friend could not find an original M23 armament subsytem ammo box for his Blain cosplay so I offered to make him one this is takes from an original army field guide and the dimensions should be correct. It is split into 3 parts that will fit a 300x300x400 printbed it is also there put through meshmixer and also just the raw CAD. I plan to add mortise and tenon joints to assist in assembly. Detail has been omitted on the back side purposely as it will rest in an ALICE frame and not be seen anywa
