https://www.youtube.com/watch?v=dPFFpa7awGs My revised version on the 550 case feeder. Allows a 1st stage for easy use of my 3d printed case collator. Uses a spare 550 primer feed return spring. the spring loaded design is less apt to jam or bind and break.I was unable to find a spring tu function properly with the first stage so im currently using a rubber band without issue. for the guide bearing i used the bearing out of a 3d printer toothed idler wheel and turned a brass wheel. Im sure a 3d printed one would also work. Only 2 pieces of the original design remain, and used some of the measurements to get the main body mounted correctly. Im hoping to get other users input and modifications to this for other calibers, I built this based on 9mm, but should easily be edited to any other caliber the 550 can handle. the lever arm can be easily flipped up out of the way to replace the shuttle if other sizes are needed. with the spring driven design nothing will jam or break in case of a double or misfeed. original design i started from https://www.thingiverse.com/thing:4266244
