About this 3D model
I made a new V2 version with a stronger lid and interchangeable label: https://makerworld.com/en/models/629726#profileId-554519 This is an ammunition box for 223, 556 rounds. The rounds can be stored individually or as strips of ten. The lid has a snap device. When using for 300 BLK ammunition, please first print a box and test whether the ammunition fits. The box may need to be scaled slightly.
