I wanted a storage pouch that I could carry on my person during outdoor activities with friends, capable of holding plenty of spare quick-load soft BBs. Inspired by the shoulder-mounted pouches seen in movies and TV shows, I designed this one.

Print as many units as you need, adjusting the crossbody strap length to suit your preferences.

Each unit can hold four pepperbox-style quick-load BB magazines; you’ll need four M4 nuts and M4 x 30 screws, as well as several pieces of 5-cm-wide hook-and-loop tape.
