So far I have printed out the 9mm and .45 feeder dies. I am printing the .223 die now. These things are pretty cool. I haven't actually tested anything yet. I am going to slowly start working on recreating them, starting with the screw in die. That part can be somewhat standard I think, just with varying internal diameters. The part that slides in is a little trickier but I'm sure I can reproduce. Thing is getting the roughed out design is not usually the problem. Its working out the finer details to get the reliability, which generally means printing the part 50 times. haha
