I had a need to keep all my magazines in the safe and range bag organized, together and as compact as possible. Offered to you is my take on the solution.

Printing with PLA on a Ender 3 on the finest settings took 3+ Hours, but it's strong and the magazines mostly slide in with a good friction fit.
