.223/5.56 Stripper Clip Box

Phillip did an excellent job with his box and as printed the lid is a tight friction fit. 

I did not want to use latches. I sliced both the lid & the box lengthwise, mirrored the hinge halves, and combined the halves.  For hinge pins I used 4-40 x 1-½"  screws and slotted one of the lid hinges for a nut to help hold the hinge screw.  You can use a paper clip/bobby pin hold the lid closed but friction fit is tight enough for loaded box on its side or upright.
