AEA Megalodon 50 cal just havin tons of fun. link for the shotshell file, I printed in spiral mode at .24 layer hight, .33mm wall thickness and 2 bottom layer for the body and 4 bottom layer for the cap. adjust size to fit your bore or magazine. caps should just pressure fit to shell , no glue needed and I also spray them with silicone spray and let dry. :4332876
