Airsoft Barrel Plug Clip

Wanted to make something easy to plug the barrel when not on the field. Should fit most airsoft rifles. Should also be easy to clip to your vest / keychain or put in a pocket.

V1 (removed, but still pictured) - Removed due to post print mods needed to make it work
V2 (newest/current) - Shortened barrel plug, rounded plug, reduced diameter from 6mm to 5.5mm.
V3 (in progress) - Plan to add other features...carabiner hole, wider version for bigger rifle tips
