Standard 22 Moderator 1/2 UNF x 20

[elguapo99]

Old Crow,
Thanks for sharing your designs. I printed the standard .22 (4 times) and .25 version on my Qidi Q1 Pro using Elegoo Rapid PETG and they printed perfectly. They are by far the quietest moderators I have tried. The only sound now from my P15 .25 cal is the ping from the hammer strike. I've tried many different moderators to quiet my Artemis PP700 S/A pistol and none have worked until this one. My other .22's are all dead quiet now.
Thanks again,
Bob

I printed the Standard 22 and the Wraith earlier this week on my Prusa MK4S, with Jessie PETG (from Printed Solid).  They were both easy prints, and fast using a 0.25mm layer height.  And the threads printed out very well, I didn't even need to chase them with a tap (whenever I model threads they usually print too tight). My son's spring break is next week and hopefully the weather here will be favorable to try them out.

Thank you, sir!  Pleased to hear it.

I hope it works out well for you.

Hi Mike,

I just sliced your Archangel mod, and Orcaslicer keeps warning me that there are "floating regions" in it. I opened the STL just as -is, I put 8 walls and 100% infill, and it is sitting flat on the build plate in the slicer. Any ideas?

Hi Jared, the problem you are seeing is caused by the larger flat areas being bridged at the top of the print.  I have not tried to print that design on an FDM printer and it may not work.  I have printed all the other models on an FDM printer and some of them have the same issue. They all print fine. I can chamfer the edge of that section in the next update and the warning will go away.

Personally I'd ignore that warning in that particular file but that is a decision you should make.  Ill make that correction in the file and upload updates today.

That one is somewhat "excessive" but it's pretty quiet.     I have just about finished the changes.

Fixed the problem.

I'll post an image of the area causing the warning and a print of that part of the moderator so people will know what to expect.

Here are images of the attachment section of the Archangel 22 moderator.  I printed it separately and oriented "muzzle down" as the designs recommend.  Printed at a 0.20 layer height in PETG on my Bamboo P1S.  I had vertical walls set to 2.  Yours should be set to 5 or more.  Usually I set them so that the walls of the moderator print with no infill.  That alone generally solves this problem.

The warning we are seeing is caused by the flat spot where the threads are reinforced.  You probably won't get that warning as I think I've fixed it.
If you do you can safely ignore it and the result will look like the included images.

During post processing you can pull, burn, cut or melt out those "fuzzies", if they even appear in you print.  I usually just reach into the moderator with forceps and pick them out.

Anyway that's what WAS causing that warning on the 60mm and larger diameter designs.

Surprisingly that archangel can fit on my Sumatra. But I won't be testing it until I get more paint just in case the paint is what is making the moderators stronger since all the moderators I've tested except one have blown apart unless they were painted.

Welp, if it blows up on the Sumatra, let me know.  I'll run something off that should hold together but you'd be better off to  look up "lost PLA casting" as the end product would be more efficient and probably weigh a bit less.

I know. That sort of rifle just really isn't made to be silenced. It want's to be heard. The testing of all the cans is fun though, and I do have one that does quiet it down to an almost civilized level.

Well if it holds up more one shot I'd be surprised.  The walls on that one are only 2 mm thick.  Good luck I'll be watching. 🙃

[bduares]

I did print the file at 100% infill with 8 wall loops so it might take a shot or two after I paint it

Updated with another design.   I still have a couple of designs that need to be uploaded.  Perhaps later this week I can get another one up there.  It looks like I've uploaded the entire three baffle family of designs.  There appear to be two or three two baffle designs which remain. to be uploaded.

Mike,

Your Thingyverse post seems to have changed.  Is that because of a cross structure that can be seen in the bore of the original STL?  Image below

Hmm

That is a logical error in the code which I was seeing the other day when I was fixing the warning we were seeing in the slicers.  I did not know that I had posted any stl/3mf that had that error in it.  I see now that it is only occurring with the 17 cal moderators.  I introduced it when I was fixing that warning message over the weekend.  Thanks for picking it up.  You saved me a bit of work.  Ive removed the offending file and checked all the others.  That was the only one which had the problem AFIAK.

I should probably explain that a bit better.  Everything I post is done in OpenSCAD.  I wrote about 800 lines of code so that I could just alter a config file and then have OpenSCAD generate the stl file.  For a while I also maintained some batch files which just ran OpenSCAD from the command line and changed the values of the parameters for each run.  One command and all the stls for every design "popped" out.  Recently I cleaned up the code, removed a bunch of cruft and streamlined the processing.  At that point I dispensed with the batch files and simply modify the config file when I want to generate one of the designs in my catalogue.

All of my designs come from the same basic study.  That is the study I referenced in the first post.  That took us about two and a half or three years.  It is done now and I am releasing the results on thingivers.  Sometimes someone will find a problem and I'll fix it in the code and generate new copies of the designs impacted.  In this specific case only the 17 caliber designs were impacted and only the ones I posted today.  That is fixed as of just a few minutes ago.

Thanks!

Mike,
I just re-DLed the thingiverse archive "all files" and found that the 177 version of the STL is now missing.

Thanks for posting all of these, I'm sure they'll get a lot of use!

[OldCrow]

You are very welcome, sir.

There was an issue with that one.  Which I am fixing just now.  It will be up again shortly (I hope).

Mike

[TorqueMaster]

The current thingiverse upload has the 177 now, and all the STLs all look correct.  Thanks again!
