Simple 10+2 AmmoBox for .308 Win Rounds. (7,62x51 NATO)
Box closes with a nice snap.
Idea came from: https://www.thingiverse.com/thing:5661539
But its fully recreated from scratch as a little Fusion360 training.
10+2 came from the idea to always shoot sequences of 10 on the shooting range + a little reserve or warmup shots.
