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 advise.

huzzzah!

EDIT: i printed this.. quite the opposite. the bbs dont fit into the holes. I was banking on the 5.95 BB would have clearance on a 6.00 mm channel. NOPE.. ill increase clearance to 6.08mm

EDIT: tested, adjusted the diameter of the barrels. nice sealed fit. with 2 in each barrel, total of 6 rounds. it has a 10 ft spread @ 50ft with flat trajectory.
