Update 8th of February 2025: Added a separate 3mf file with 6U height boxes. Update 4th of January 2025: Added 4x4 grid size box for 169 rounds. This is the max A1 Mini can handle. 9mm Gridfinity ammo storage boxes with locking lids - 2x1, 2x2, 4x2 and 4x4 grids. 2x1 9mm ammo box holds 21 rounds, 2x2 holds 49 rounds, 4x2 holds 98 9mm rounds and 4x4 holds 169. All ammo boxes are stackable and custom height this time, but I can add U sizes if needed. Just let me know. The last photo also shows my 308 Gridfinity compatible reloading tray.
