I wanted a simple but stackable ammo box for 6.5CM so I made this. The lid has a small detent to help hold it on (probably not range bag safe). The boxes are stackable and will print without supports on any printer. Cartridge dividers are sized so spent cases can be put back in with enough sticking up so you can grab it with a fingernail for the reloaders and brass goblins (like me). This is a big print but uses very little material because of all the empty space.

Revision 1: Added a slot in the front for putting load data sheet or a 3d printed label.

Revision 2: Added a 3d printed tag for the tag holder to the 3mf. You can use the Make My Sign tool in MakerLab to make this (I didn't because I didn't think about it). Tag is 43.6 mm wide x 45.6 mm tall with a .6 mm thickness.
