These designs can be used to extend the new arp9 68rnd mags.
The small extends it to around 84 bbs, and the big one to 104 bbs. I didn't test the medium one.
You'll need new springs. I just cut up the mag spring of an M4 midcap. I cut the spring 30mm longer than the bottom of the mag extension to ensure proper spring pressure
V2 Update:
I've found that V1 would crack at the edges when dropped. V2 is a lot more sturdy.
V2 is made up of 3 pieces and you'll need 4 m2 bolts and nuts. I cut some longer bolts to 27mm, but 26mm might work as well.
Keep the metal pin in the original mag part, as it's still needed to stop the extension from sliding off. V2 also only exists in the biggest size
I also added flat versions for easier printing
Mine are a bit ugly, as I don't care much about the look of the undersides of my prints
