Mossberg 590A1 limiter plug

The limiter that came with my Mossberg 590A1 was a 5mm thick metal rod with a disc welled at one end. Right away there was an issue with the metal rod being misaligned with the center of the magazine tube. The big issue came later when the disc holding it in place broke so the rod just fell in the tube. I designed a plug that holds the rod secure in place. Simple design, does not need supports to print it. I used PETG for better thermal efficiency with 1 outside layer and 100% infill.
I designed 2 models, v1 is for shotguns with a flat tube end, v2 is the one I am using with thick screw for the 590A1.
