This Nerf Elite dart magazine is an extended version. It should hold 14 darts, but it might only do 13 depending on the spring materiel. All of the parts are possible to print in a 220x220x250 print volume.
This design requires 2 M3 nuts and bolts, but it can be held together with other screws. Just find one you think might work, and maybe widen the holes with a drill to accommodate.
The magazine will run a little bit smoother if you print the shuttle and body at a lower layer height.
To assemble, slide the shuttle into the body, with the rounded part facing towards the top. Then, place two half springs into the body, with the flat parts touching. After that, screw the cap onto the bottom.
