This is a collaborative effort between qwertyaardvark who designed the shell retention, and me who designed the form factor to fit into the Aridus QDC. We came up with this at a time when Aridus QDC inserts were hard to come by. I've printed these and put them through their paces in several shotgun classes and they seem to perform pretty well, although I would never use these as replacements for actual Aridus QDC inserts in a duty capacity, home defense, or any real world scenario where your life or someone else's would depend on it. These are strictly for use in training and recreational shooting.

I typically print these in PETG at 100% infill for strength and rigidity. The retention mechanism should still be able to flex enough to allow the shells to slide in and out but retain them under recoil. I have had some success with PLA+, however the flexibility in PETG filament seems to be more suitable for this application in my experience. No supports needed if printed with shell carrier oriented up or down.

Please note that I have experienced some issues in really cold weather where the printed shell carrier contracts making it a little harder to extract shells which is why I don't recommend these shell carriers for any serious application.
