.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 it was surprisingly OK. I am printing it base down 100% fill. It has a hole for an M2.5 set screw to be added for retention but it seems to stay ok with just friction. I use only 1 or 2 perimeter shells and turn my cooling fan to 30% when printing horizontal i.e. base down with JV EXTENDER on build plate. It was breaking and delaminating at the retention slot prior to this. It is coming out very strong now, I think the perimeter layers were too close to the retention slot cutout Printed vertical it is extremely strong but requires supports or some good cooling to bridge the top layers. I've printed it with 50% fill and 4 perimeter layers plus 100% cooling fan in the vertical orientation with good results. I did some drop tests and it survived but have not used it in a match yet. Made this for my AICS 10 rounders for use in PRS matches. I think it can be made tough enough to be used in matches.
