Shim for Ammo Can Lid

thingiverse

Ammo cans are great for storing small things that you want to keep dry and protected. But the lids are designed to be easily removable so can tend to fall off unintentionally. This is usually not much of an issue for military surplus products. But if you buy a new one, the lid is likely to be loose and cause issues. This is a simple shim that rests between the hinge barrels to prevent them from sliding out, and the lid falling off. Designed for 30 caliber (medium) ammo cans. Update 8/28/20: Added a design for smaller (~3.5 in wide) ammo cans.
