APS MKII quick loading shells

Was browsing their website and this seemed like a great idea. no more futsing around with wads etc. just load up the bbs and done.

Edit: as of now im marking this as a WIP, i have NOT printed this and i see the bbs CAN fall out from the top. I plan to use a solder iron to just make a nub at the front to prevent this and add some retention. ALSO there is a SMALL area of bridging inside of the shell which shouldnt be a problem but we will see. If anyone beats me to the testing phase, please ad
