I'm using Cura and when it came to the horizontal surface closing the cylinder, the two screw holes caused a huge problem. Cura tried to print the hole outlines in mid air and things quickly became a mess with hanging filament getting stuck everywhere.

    How do you print this part without supports with those screw holes? Is there some advanced slicer options that you are using to accomplish this? I have been looking but haven't found anything that looks like it would help.

    Thanks,

    Pete
    Hi Pete. It looks like this is not illustrated correctly in the manual. This post shows the correct orientation for printing.

    As promised: The two main parts to the new .38 caliber bullet feed die are done, 3rd out of 4 printing. Quality is way better printing one at a time, least ways on my Creality CR-10 v2.

    So here's the first try.....just feeding on my Summit to a .357 mag case. Works as well as any other. Case height is only 1/4" higher than .38 special.

    Green again....because settings are right for that filament....and I'm feeling lazy today!



    Batting a 1000 on this one Tyler! Perfecto! I only had to hand twist a drill bit inside the insert for about 5 seconds, and use an exacto knife for a single inside string inside the die barrel....and 5 seconds. Oh and just a single turn with the knife in each ball bearing hole.....Easiest one yet!

    Thanks to all that have contributed to this epic thread, my main body is printing as I type.
    One question I have not found an answer to yet, which collator plate is suitable for .38spl / .357 magnum pistol brass base down please?

    Does anyone have pictures of assembled nose down bullets feed to Lee APP ? My imagination fails me here I'm planning to use light sensor but I guess any kind of sensor tube would be similar in assembly.

    Good question as it seems 99% of the help is for cases that are rimless. I'm assuming you know that "custom" plates made from the Openscad plate builder, so you should have Openscad the free programmer's cad program loaded, right?

    I'm including a snip&sketch of the .357 measurements converted to MM, which is what the 3D printing world lives by:



    You'll notice that the rim diameter is included, and it's that diameter that must fit in the holes around the brass plate you want to print.

    So the 11.2mm rim diameter is critical....the holes have to be bigger than that or they won't drop. Well .45 caliber is 11.5mm. That entered into the Openscad Plate builder would be minimum. TylerR may have more experience doing .357, so his input would be important, but on my Pre 3Dprinter mod of my old Hornady Pistol bullet feeder, I drilled .50 caliber holes all around, and guess what. It collates .45, .40, .357, 9mm BULLETS all on one plate. But.......this is cases. But I would still think the ability to drop is the same. The holes need to be big enough not to have a lot of near misses, IOW's cases that ride around the merry-go-round tilted, but not dropped all the way.

    For case feeders TylerR has already noted that there doesn't have to be a plate for every caliber, so maybe one of the plates already in .stl file list will do you, he'll be by soon and let you know. But pay attention to the slider and the drop tube.....I think he will guide you on that too.

    I still need to add one more case feeder to my already very crowded assembly line to drop pistol cases into my original Pro 2000, which is why the last thing I printed was .357 parts...... So bullets are handled for me.....cases next.

    I have used the regular small pistol base down brass plate to feed 357 mag case into the APP with some success. It will bind up on occasion when a case hasn't completely dropped, but slowing the speed down substantially reduces that.

    I was wondering about making a plate for revolver cases that is more like the 45-70 & rifle plates, where the cases would feed on their side vs standing up. Anyone tried that or have thoughts about it?

    There is a picture in the images folder, and there is also a video in the manual. There are about 10 ways to skin this cat, so it is hard to give a straight answer. Do you plan to mount the sensor under the collator or on top of the APP press? Do you want to use the APP clear tubes at all? Do you want to use the offset connectors, or just have a straight shot up?

    I do not load .357. I have not done any testing with rimmed cases. At some point I will get around to figuring out .44mag

    Edited: I just ran a quick test with a piece of .38 special brass and the large pistol brass plate. It worked well (better then the small plate), so I would start there. The idea of feeding them on their side may also possibly work.

    Betcha the large pistol base down brass plate would work a lot better.

    Interesting idea about sideways. However for a case that short, you'd multiply in spades the incidence of the "standing soldier" problem we've seen with even tall rifle cases........so......you'd have to mount something to knock them over inside the collator like I did with rifle cases. See video below:

    I have generated a plate to try side ways and just started printing it. I'll try to report back in a few days how well it works.

    Any suggestions about how the slide adjuster on the slide plate should be set?

    Thank you GWS, Tyler and Ranger, I look forward to hearing how the sideways plate goes.

    Thanks Tyler, I guess number of options is what got me confused. What I was planning to do is to use provided bracket, have sensor mounted on the press and not use Lee's tubes, also didn't plan to use offset connector. I did find one image related to APP and it was using offset connector.

    Simplest would be to go Drop_Tube -> APP_Drop_Tube_APP_Insert -> APP_Bullet_Insert. You just need to select the correct ones for the caliber you are trying to do. With the APP_Drop_Tube_APP_Insert there is only a small/medium/large. You don't want one too big, so it may be necessary to pick the smaller size and open it up with a file a little bit.

    Hope that helps.

    These were just posted btw.
