Those chasing accuracy won't be satisfied. I plan to print a spacer for the bushing because the end mill has flutes in contact with the bearing instead of shaft, so I need to shift it up ~.2". I will continue to play around with this, but it's usable as is, and has room for improvement. I just got a standard shaft collar and don't feel e need for the fancy adjustable one at this time. https://www.ar15.com/media/mediaFiles/102025/D8FF9A41-CAF4-4FEE-9FBC-1AD03AE77B21_jpe-1801290.JPGhttps://www.ar15.com/media/mediaFiles/102025/39EB7175-F8A5-44A1-8121-963C34289978_jpe-1801291.JPGhttps://www.ar15.com/media/mediaFiles/102025/38059A07-78E0-4600-B227-852AB8EB9FB2_jpe-1801292.JPG Those are the reasons I'm designing my own. There's a dilemma with the bushing fit - you can't simply scale it because the bushing fit within the bearing and shell case fit in the bushing both need to be correct. One of the reasons I bumped up the bearing size on that end is because you have a wider inner race for the bushing which should provide less angular play (as well as allowing enough wall thickness for an O-ring groove in the bushing and also accommodating short mag cases). The end mill length of cut and overall length work for his particular end mill (1/2" length of cut), but it needs to be different with a standard end mill. My design is already done, but I'm just waiting on parts now! The Giraud and WFT are certainly nicer trimmers, but cost significantly more. Also the Giraud seems to be caliber specific so it's going to cost you an additional $100 for each different type - in the case of the 3D printed version, it's a matter of printing a 12 cent bushing. I think I'm in for about $25 in parts right now, which includes an American made carbide end mill (that doesn't even come standard on the WFT). |

Could you explain the o-ring? Is it going in the ID of the bushing to center the case? My redesigned .223 bushing should be done in an hour or so. Tightened everything up and moved endmill forward. |

I could do a single wrap of friction tape on the exterior to tighten the bushing within the large bearing, but the interior just simply isn't tight enough to hold the case for a square cut. In fact I'd expect more uneven cuts from mine than milsurpninja's photo on prior page. Bummer. |

I've been working on a new bullet tray design for the Hornady LNL. Dropped tray down lower and sloped sides for more volume. Makes it easier to grab bullets down lower. I'm going to have a tray larger than this too. Something was off on my dovetail on this one but once I get that worked out I'll upload to thingiverse.

The reason I ask if you use any design software is because I could possibly send you a file where the inner and outer bushing are separate bodies and then you could tweak them each individually and then merge. Fusion 360 is free for a year, but then you just have to renew your hobby license each year. No cost involved as far as I know. |

I've tightened up the dimensions and used the proper case profile. Another thing to consider is whether or not the brass has been resized or if it is formed to the chamber, but these are things we'll just have to play with. Also, the taper on the outside of the original bushing is a nice design touch, but I got rid of it because I don't like to constrain wall thickness on things like this - FDM printing tolerances start to vary even more as the wall thicknesses get small. It will be a tight fit depending on your printer/settings (I left .1mm clearance), but let me know how it works and I can modify as needed.

I wonder how well my old Mac laptop will handle these programs, and in fact I'm sure I'll be forced to update my OS too  It'd probably be worth it to be able to do this kind of thing though. And again, thank you! |
| So an update, that bushing fits the case absolutely perfectly without any wiggle at all. I've still got to make some adjustments and reprint the locking collar so I couldn't actually test it, but this new bushing seems like a yuuuuge upgrade from the original design. |

I don't have an inline fab handle, so can't test for clearance there. I might could move the dovetail to the left some more if it does interfere. I'll need someone to test it and get some measurements how far over it needs to move. Files not quite ready yet. Something wasn't right with my drop down dovetail. I double checked my drawing file and can't figure it out. Tray fit perfect on my other dovetails so don't think it's the tray part. Maybe for some reason it didn't print to the right dimensions? I travel for work Mon-Thurs, so can't do more testing till later in the week. The biggest tray will be about 6.25 inches x 4.25 inches. I could probably go bigger, but that's the size of boxes I have for shipping them out when I'm going to sell them later. I have no doubt this thing can handle the weight of a few hundred 45 acp bullets. Best thing I did was move away from the clip on design for the tray clip. The new screw on design opens up a whole new world of options. |

I'll see what I can come up with. This will give me something to work on when I'm in the hotel this week. I was thinking it stuck out too far too, but made best sense for ease of printing. Hornady has some weird angles to work around to get it to line up where the tray appears straight from the front of the press. Then to complicate matters they have 2 different bar designs. |

Might help index it and provide some lateral support too? Possibly add some double stick tape to the sides and it would be rock solid. I have the inline fabrication mount with double bins and have always kept the bullets in the far left bin. After a few hundred rounds my shoulder is killing me from all the movement.

The weight of the bullets holds it solid with the tapered dovetail design. More weight means more solid lock. I'll try it with my larger tray design and see how it does. Your light should fit over the clip. The clip is 5mm thick. I tried to keep it thin but strong there. |

I finally got my trimmer design built and ran a few .223 cases through it - seems pretty consistent and each one was within a thousandth. Cut quality seems good too, and it should require little chamfer work. Also, I decided to design my own stop clamp and that design holds well - I was really trying to keep width at a minimum to ensure plenty of shank for the drill chuck. All of that being said, I've got the idea to eliminate the bearing where that cartridge case bushing sits. I don't think it's really needed, and the O-ring does a great job of holding and centering that case bushing. I'll post up STL and parts links for anyone that wants to make it.

Additionally, it uses the same R6-2RS bearing that the Thingiverse design does. |

So I finally got my Case Trimmer MK2 designed and printed, and initial testing is very good. Consistency is every bit as good as the first one I made, and it should theoretically be even better since any additional slop coming from the front bearing is no longer there. The only noticeable variation in the system now is the R6-2RS bearing that the end mill rides in - the clearance within the bearing allows very slight changes in angular alignment when inspecting it, but all the brass I've trimmed appears to be quite square. I'll post a download link to everything shortly. I also pulled up the SAAMI specs online and went a little crazy with bushing designs, since those are pretty easy to draw up. Let me know if there are any good casings you're interested in. I also made a little tool to pop the bushings out since the O-ring grabs well in the bore (you could actually get away with no O-ring, but I like the way it positively holds the bushing in).

I'm trying to avoid printing anything that needs supports. Everyone is giving me great ideas which only make the final product better. Just got in from a long week of work. Printing my offset dovetail and my largest tray design just to see how it mocks up tomorrow. Nearly a 9 hour wait now and that's with a 0.6mm nozzle. With a 0.4mm nozzle it would be 18 hours. |

Just completed and uploaded the MK4 version of my trimmer! I doubled up the R6 bearing, which made a huge difference in angular alignment of the endmill. Not that the previous version was bad - the trimmed cases seemed to be quite square in the jaws of my caliper and they were very consistent in length. It's just that a C3 rated ball bearing has a bit of slop, and I could see more angular movement than I liked.

Finally got my printer up and running. Time to print some stuff! So far I've printed replacement parts for my fridge, a light fury (for my daughter), and a sword end from game of thrones (for my brother). They all turned out shockingly well. Time to move on to some more advanced stuff! |

It's just that a C3 rated ball bearing has a bit of slop, and I could see more angular movement than I liked.

I printed both versions of the 223 bushing and the tight one is a hair too tight for me, but the other seems dead nuts. Bearings are solid as well. I did the mk4 btw. Will work on the snip now and then reprint this baby! |

Finally got the 6.5 Creedmoor setup running at least on the bench. Got the 6.5 Creedmoor bullet feeder die working now also.  New 7mm Die I'll be doing a dry run on my Hornady LnL AP Progressive this afternoon. I think that my 12mm diameter spring tube may be too big. |
