This is a remix of one of my favorite ammo boxes. It holds 50 cases. I liked the original but wanted one for 5.56. The ones pictured were all printed in PETG and work great. Only the latch and latch hinge need support. The second picture shows how I printed them. The seals were printed in TPU.
The author remixed this model.
This one uses 5x m2.5x20 and 2x m2.5x30 screws. Everything was made smaller and the box dimensions were changed to fit standard 5.56 cartridges.
