How is everyone getting the super safety’s made in metal? I have seen that some cast them. Is there another cleaner option?

Widened the hitchhikers shoulder piece and lock belonging to the retractable stock assembly. It doesn't interfere with ejection so the ump can be fired from all positions. It's a little wobbly fully extended in it's current iteration. It's 27.5 inches extended with the muzzle device shown so it's not quite an SBR. I'm not finished yet but if there's enough interest I'll upload its current iteration on my od account after work. I plan on modifying the rails and lock to get more stability out of them fully extended.

I would like to avoid uploading fingerprints for an EFT file if possible. Has anyone submitted one set of (2) FD-258 cards for a batch of Form 1s? If I need two cards for every Form 1 cover letter I will probably get over my aversion to uploading the cards to generate an EFT.

The TX22 Pillager Chassis V2 is finally released. I never actually made a public release of the V1 as there were too many things that just weren't ready. I plan on making this chassis design in other platforms. I would like some suggestions if the people wouldn't mind. I have already made a beta PY2A Glock 20 version.

So, I've ran through pretty much all of my ammo recently. Started up the ender3 this week to get ready for warmer weather.

Going to launch the next round of 43R ammo in the next 2 weeks. With the "precision slugs", we hit steel at over 100 yards! Other rounds include optimized beginner loads, a load for signals, 2 precision slugs, and an optimized load for .177 steel BBs.

this is in the Qidi slicer so just find these same 2 settings in yours and give it a shot, my supports work very well but also pull off with zero left behind and little effort.. this isnt a cure all for everyone obv but its a starting point and should solve quite a few ppls issue

I've had my parts kit laying around since the fist drop of the nylaug. I'm hopefully getting everything together to print some PA6 for the first time. Once I get that figured out I want to finally get the nylaug going. I see there are a few places with aluminum trunnions. Is this necessary or a worthwhile upgrade? Any other tips before starting?

Does anyone know of an off the shelf way to use a tri lug adapter on the new FTN.5 Rifle cans? If not, is it as simple as modifying the thread adapter insert STL to take the threads of an off the shelf tri-lug adapter?

Never used CAD and this might be the project to get me to learn. I really want a white monster can hanging off the end of an MP5

Has anyone tried Polymaker's PolyMax PLA? Is it worth paying extra for? I see that Polymaker's PLA Pro is what seems to be the gold-standard for stronger PLA, but could this be a better option? How would it hold up for lowers or cans compared to the PLA Pro? Not factoring in heat-resistance.

The other day, I conducted my first live-fire test of the MPA Defender FRT I designed. Unfortunately, it seems to have a couple of issues.

1. I've been having consistent OOB detonations (photos shown at end of video). Nothing has been damaged as a result of the 98 rounds I tested with, and none of the casings I looked at had blowouts. However, it's still concerning, and I'm not sure if I could release it like this in good conscience.
2. The FRT wears out way too quickly. The first one lasted about 47 rounds, and the second 51 rounds (in Polymaker PLA pro).

To stop it from wearing out, I've been pondering some ideas for cutting out the part that touches the bolt from a metal blank and screwing it on, and have tinkered with making some printed jigs for cutting said part. I've also considered printing it out of a stronger filament like PA612-CF or PA6-CF, but I'm unsure if these would work well.

To stop the OOB detonations. I have no clue what to do.

Another hurdle is that I have just

Swear I remember a filter for the bersa thunder. Bought a kit stupid cheap, but I can't find the file. Can anyone point me in the right direction? Or am I imagining things?

I just want to see what printable handguard options there are out there for old school standard AR uppers with spring retained handguard using the front sight post.

I've done a total of about 11 hours (3 of those over the last week) of searching for them over the last 2-3 years and I don't think I've found a single normal handguard that wasn't a free float. It's kind of blowing my mind, especially after looking at large sites like gatalog. I've kind of given up at this point, and don't know where else to look so I figured I would start asking around.

I'm not picky, but I wouldn't mind seeing some classic handguard designs and possibly some with m-lok if any exist. I appreciate anything even remotely relevant though because I haven't found one. I finally gave up and went to ask on r/fosscad on reddit, and now I'm here... Finally.

Again, thanks to anyone who takes a second to send me a link to one.

Will be SBR'ing one of the MP5's and decided to give this one some attention. Standard Leberator (Leber with an AR grip) that I added some textured/dimpled area to so it would break up the flat featureless panel look. Pretty pleased with how it turned out.

After the Form-1 goes through, will probably go with the usual Magpul collapsible stock and their short VFG.

i know i remember seeing him say somewhere that hes getting really nice results with .6 nozzle at .12(?) layer height and .5(?) for the rest of the lines.

my question is are those the actually the correct settings or am i misremembering? i been trying to find where i saw his post but im starting to think this may have been Mandela Effected

Is there any other variants or modifications anyone is familiar with? The most obvious iteration would be different calibers, alt designs (such as changing rachet arm spring retention from a post to a recess)

As an update (as always, shoutout to TheAmazingX, I only took their idea and improved on it for manufacturing).

No Drill SCSSS is fully released, it has been confirmed working, and I have yet to hear of a failure in the field (if you have, please let me know so I can capture it).
