This does work but is ammo finicky. 855 runs through, wolf not so much. It will take some rounds to "break in" hopefully before it just breaks. Its a reasonable print for individual pieces so not the end of the world if it breaks. I'm getting a slight binding at the projo tip at the 90 deg transition which does not lead itself to ease of mechanical resurfacing. I'll see if I can tweak a couple thou out of the STL to compensate.

I printed one a few months ago, I got the files from Boostwillis as well. It runs ok. .223 is better than .300ACC. I did have to do some light sanding on mine around the ejection port contact faces. I printed the follower, and base in PLA, and the frame in PLA Prime. Not sure if it would perform any better/worse with PETG or another material. Chatting with Boostwillis, he said he tweaked the follower a few different times, but found its limitations. I noticed that mine would not seat the last round 100% without rocking the entire loader upwards before removing it from the ejection port.
I think I may use it as a 5 round loader while just putting holes in paper at the range.

I may use these and see if I can modify the 3D models for a left hand ejection port. This will be a "lifesaver" if I can do this successfully (for @TPatriot at least). Unsurprisingly, I have not been able to find any LH ejection port loaders anywhere. Mean Arms explicitly state on their website that their MA Loader won't work on LH uppers, and I own two BF-10s that also clearly cannot work if reversed, as they would be feeding upwards into the receiver. Don't expect any movement on my initial statement for a fair while (I have an increasingly busy schedule, don't we all), but I will certainly share if or when I do.

What slicing software are you using? Cura has a mirroring feature to just make right and left handed prints.

I use CAD (SolidWorks 2019, PTC Creo 4.0) for work, so I was planning on converting from the STEP files and mirroring parts using that software. I also planned on making any modifications as needed, both cosmetic and functional. I don't personally own a 3D printer, but my friend has a few that he's letting me use. My only experience thus far with 3D printing are 3rd party companies (for work) and our in-house printer(s) that I don't have any business running on my own.What slicing software are you using?

I use Unigraphics NX at work. If you have solid works, then you have this covered! Enjoy!

I would inquire in some of the printing boards. It doesn't exist as far as I know but it doesnt mean someone cannot modify the stl for what you are looking for.
