Description

So this is another example of things Putz breaks on his press and has to design a new one. In this case I had a 9mm bullet get wedged at an angle in the bullet chute and then proceed to catch on the next bullet and take a chunk off the original bullet chute. As with a lot of the 3d printed original items on Dillon presses it is made thin. This is a little more robust. I have found so far that this seems to work better than the original because the original would occasionally (way to often) have a bullet get wedged at an angle in the chute thus blocking further bullets from sliding down the spring. This would necessitate me taping on the offending bullet to dislodge it so it could continue to feed. So far I have not had that problem with this design (yet). I have even cranked up the speed on the rotation of the feeder and it still works well. Now for directions and materials. I used one 3mm knurled nut and one 3mm cap head screw. On the design you will see one hole has an offset that is bigger in diameter than the other side. Put the knurled nut in the SMALLER diameter side. The larger diameter offset hole should fit the head of the 3mm cap screw so that the screw head will fit flush. Before melting the knurled nut into place I suggest putting the screw in from the other side and threading a couple of thread deep into the nut... then apply heat to the nut. This keeps plastic from oozing into the threads. Finding the screw won't thread in due to the plastic in the threads because you forgot to do this step will make you say bad words. I know because it has happened to me. I printed this on a Bambu P2S. Print in the orientation shown in the cad drawings. Do not use the auto rotate feature on bambu labs because it usually sets it at some odd orientation that won't work. Can be printed in PLA or PETG. Mine was printed with PLA. For setting I used infill of 50% with support enabled. Change the angle of the support threshold from the default 30 degrees to 90 degrees. This is so the offset in the end where the spring attaches to print without stringing. Also uncheck the box that says remove small overhangs otherwise it won't print the small offset for the spring at all. Make sure you do not over tighten the 3mm screw on the spring or it will deform the spring enough to not feed. Update on this: I have run about 200 rounds through the machine without a single bullet miss feeding or jamming. Loading 9mm RN Berry bullets 124g. Will try with some 124 JHP and 115 JHP and post result later.
AI Analysis: This object is a mechanical part designed for a bullet feeder system, specifically for handling 9mm ammunition. It features a blue plastic component that guides bullets into a feeding mechanism, with a coiled spring and a threaded assembly to secure the bullets in place. The component is shown in close-up with several copper-colored bullets visible, indicating its function in a shooting or ammunition handling setup.
