C308/HK91/G3/PTR91/CETME Magazine cover

This is a cover for C308/HK91/G3/PTR91/Cetme magazines to protect the feed lips. You can print them in different colors to indicate ammo types. I started with the shape from https://www.thingiverse.com/thing:1320532 and cut it down to just fit over the end of the magazine and thinned the sides. I can't get Thingiverse to call this a remix.I printed it in PLA/PHA for strength.
