Shotshell reference model

This is a NON-FUNCTIONAL reference model of an Evike Zombie Stopper Shell. It is intended to be used to aid in the design process that was included with my M4 AEG Shotshell Adapter. I am uploading it separately so other people can use it without having to download the entire magazine, and so it is easier to find for people who just want the shell model.
It can also be printed out and used to test fitment with parts if you lack a real shotshell to test with.
It can also be used to print dummy shells for cosplay or decorative purposes.
