.308 AICS Magazine - 2 Round Base Plate Extension

thingiverse

Print it in PETG if you want it to last; I prototyped it in PLA and surprisingly, it was okay. I'm printing it base down with a 100% fill. It has a hole for an M2.5 set screw to add retention but it stays put with just friction. I use only one or two perimeter shells and turn my cooling fan to 30% when printing horizontal, i.e., base down with JV EXTENDER on the build plate. Before this adjustment, it was breaking and delaminating at the retention slot. Now, it comes out very strong; I think the perimeter layers were too close to the retention slot cutout. Printed vertically, it is extremely strong but requires supports or good cooling to bridge the top layers. I've printed it with a 50% fill and four perimeter layers plus a 100% cooling fan in the vertical orientation, with good results. I did some drop tests and it survived, but I haven't used it yet in a match. This was made for my AICS 10 rounders to use in PRS matches. I believe it can be made tough enough for actual competition.
