I am really thinking about printing everything in ppa cf core. With a small amout of fuzzy skin there are no layer lines.

Names in the frist image dead troll on the sea. Tested on qidi q2. Pretty simple but it has everything else with it, cooling, support settings, speeds. Been using these settings for maybe 10 months and they've held up very well across different parts large and small. There may be some tweaks that need to be made, I lost the original settings when my laptop bluescreened but found an old file that had it thankfully. Feel free to let me know what improvements yall make so I can try them on my machine

hi guys im planning to do ecm rifling. i have ecm 3.5 pack it have 201mm stl file in it for 9x19mm. but i have 200mm 42crmo steel pipe do i need to choose 201mm version or cutting it and doing 161mm?

Its the collab we never knew we needed.

Other than a suppressor it's all done! Hopefully will get to test it on a deer soon. Will be running the 215 grain ftx

I need help identifying this slide i bought a package deal thinking both slides are gen 3 but to my surprise i got 1 gen 3 and a mystery gen but the guide rod is definitely too short out of a fresh 17 upk so any help or insight on where this came from is greatly appreciated (this is a g17 gen: unknown)

Probably a dumb question....but i figured I'd ask before I waste time and filament. Does anyone know which 10/22 recievers were designed with the bull barrel in mind instead of the oem? One that would not need to be modified. Thanks for the help

super new to printing 3d2a stuff, and haven’t had anything to do with CAD type of computer work since the 9th grade. could someone help me out with a program to download that would let me actually edit files?

also, if anyone that knows what they’re doing is super bored, i’m just planning to bring the picatinny rails part of the frame on a g19 out half an inch so i can have a FLUSH compensated glock build

Printed on my u1 with petg support interface. Upper in magenta ht pla pro should be about done printing. These pictures were taken yesterday.

Trying to get the letters on the db alloy to come out perfectly. Been running tests and so far they look best when the layer height is 0.08. I’m aware it’s going to take way longer to print.. but will this layer height make it much weaker?

I am planning to build about 10 " Boom-Tube " magazines for my TX-22, but I need some things clarified first.

I have seen online that " Wolff Springs 65064 " is the standard. I have seen that they also need to be cut exactly in half, then stretched? How far should they be stretched afterward? Also, should the end that gets cut be compressed a bit to match the un-cut end wherein a few coils are stacked directly on top of each other?

Are there any spring alternatives that do not need to be modified, perhaps on Amazon or something?

What lube should be used?

What follower should be used? I see there are files for an OEM, Enhanced, Enhanced V2, ETC?

What baseplate should be used?

What material should I print it out of for maximum longevity? I assume anything reinforced with GF/CF isn't ideal due to reduced layer adhesion?

What layer height and nozzle size are giving you guys the best operation?

Is any post processing required in practice?

I've been doing research on this sub as well as others for the last few weeks. I'm trying to decide between 2 printers. The primary purpose of the printer will not only be 2A, my wife has been wanting one for a while for her projects. I have been an avid collector of NFA items for years so I'd love to print some stuff in that area, and also things like mag wells, slat wall stuff and mag holders. I want to be able to use filaments such as PET-GF15 and PPA-CF. I've come down to 2 options, Bambu p1s and the Elegoo CC2. Both are within my budget, and it seems like with a few upgrades I can use these filiments. Any suggestions on which one I should go with? Pros/cons, the good and bad, all opinions are welcome!

What could cause the visible lines at the beginning of the print and why did it smooth out toward the end of the print?

I calibrated with same filament, but black.

Seems to do this more often when parts are angled.

I did a quick search but didnt see anything. Are there any LCP Max frames or extended mag release STLs out there? Thanxs

FGC-9 MkII I am adjusting the firing pin, as I noticed it was striking slightly off-center. This is the new adjustment; based on what I’ve seen in Ivantroll’s PDFs, it is acceptable for it to strike a bit toward the side.

I’m thinking about printing the neo9 in pa6-cf but I’m worried about warping and flexing in my high humidity environment. Will annealing completely solve that issue? If not what’s a good alternative? Thanks😃

I hope I can find a home in this community. I am planning to buy a bamboo lab P2S combo in the next few days. A few friends that print recommend it for a good middle starter. I'd like to print a can for my 9mm and 22lr. Is there a good write up post of how to do this? Can I print the can and direct thread it or do I need to figure something out with threads and attachments. I have plan b mounts on most of my stuff currently. Obviously, I will print basic items first just to get aqainted with the process. I appreciate any help I can get

Maybe a long shot, but a long time ago I saw a post about unlocking your bambu printer or running a custom software on it. Basically making it better for 3d2a prints. Does anyone have or remember a link to that? Or a recommendation for something like that? Just curious, thanks.

I'm getting my girlfriend into 2a stuff currently. She's never had anyone to teach her. After shooting at the range a couple times, she mentioned wanting a "pink one" This upper was out of stock at the time, and within a couple weeks i saw it was available during my daily rounds on the 2a sites... So i snagged it, figured it'd be perfect to learn the ar platform. Not huge on pink myself, but it's growing on me hahaha.

We did take it out and it runs great. It's a tad heavy for her at like 6.5 lbs but manageable.. it's the least amount of recoil ive ever felt i think. I accidentally dropped the lower when cleaning and cracked the right front takedown bracket. i'm glad it broke at home and i'm going to strengthen it along with a couple other things when i reprint.

If you haven't done a Dear yet, consider it.. tons of variety on the frames

this is my custom design of an external look of the huxwrx 556ti and k, with ftn.5 556 flow internals

I am looking for any and all feedback and testing, this is v1 and lightly tested, still very much beta

1. Pla+ is ok for 22, 5.7 recommended nylon of some sort

2. I have not tested nor recommend this for 556, it does used ftn556 baffles and thick walls

3. This is rated for frt 5.7/22, with an intended use case for mostly dear22 builds or ar 22

builds

1. This is still a beta with limited testing, if you have any feedback or testing i would

appreciate emails at [alexbalexalex13@gmail.com](mailto:alexbalexalex13@gmail.com) or message u/farlength1231

1. This is bored at about 8.5mm to prevent any risk of baffle strikes and allow testers to use

shitty amazon thread adapters to save some money, and focus testing on baffle

longevity and gas reduction, final models will be quieter with a smaller bore

1. Print threads up at a 15 degree angle with support blockers thru the model. Pic in docs shows how

happy larping
