21-round 5.56 ammo case. Secure lid and clear side labels. Compact, organized, and easy to access.
This 21-round 5.56 ammo case is built as dependable 3D printed gear for keeping your rounds protected and organized. The 3x7 layout keeps everything in place and easy to grab when you need it, without digging or fumbling. A secure slide-in lid keeps your ammo contained in a pack, vehicle, or range kit, while side labeling helps you identify loads at a glance. This is a pre-sliced file, ready-to-print with no tuning or setup required, so you can produce consistent results without wasted time. It fits naturally into any survival gear setup, whether you're staging supplies for field use or keeping things squared away in a homesteading workshop. Durable enough for repeated handling, it holds up to real use without adding unnecessary bulk. Works just as well in a go-bag as it does on a bench or in a truck console. It’s a simple outdoor tool that keeps your ammo where it belongs—secure, organized, and ready.
