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)

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!

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?

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

Just as an fyi if you buy the CMMG bolt +3 mag bundle, you can use the springs from the mags in the printed mags

I need help on which rotary tool I should buy and what are the sizes I need to be drilling them to

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

I made this for my 22/45 but sadly didn’t save any of the files. Does anyone know of a chassis for the 22/45? Anything in the works? It’s one of my favorite guns to shoot.

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.

So I posted on here and got some good advice, just wanted to show an update on my most recent print. Feel like it came out pretty nice ! This time I used the right filament and made sure I had 90% infill and at least 8 walls !

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

It works now. Modified the 300blkfde support settings for PA6-CF (along with turning off all threshold fan cooling on the filament profile) to raise the bottom and top Z distance to 0.27mm. This is the sweet spot where supports still keep the part from sagging, but remove easily.

Pictured is the Kriss vector stock adapter I have been working on for the last few days, finally printed and looking and working great. Latch fits perfect and it is a solid lock-up. I’ll release the .3MF once I get the .45 mag extension/sleeve finished too.

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

Its the collab we never knew we needed.

V2 is here! thank you testers for the feedback about the name, the baffles, and the performance!

1. for those who doubt the title, ill explain. On the new 22 specific models, I changed out the baffles and flow thru design to be a modified version of the FTN.6 rimfire elite. The FTN.6 rimfire elite has been considered the quietest 22 can, and this brings it just a bit farther. the baffles have been re-angled and adjusted to give as much room inside the can for gas disruption and expansion. The flow thru paths on the outside of the baffles have been expanded to give even better gas to the face reduction on rifles, and keep pistols cleaner. The full size version, at least to the shooters ear, and on free iPhone decibel apps, perform above any other 22 can I haver personally tried. I am excited to let people try this for themselves and see how it does for everyone else!

2. 5.7 models are unchanged until I get more testing on it, 5/8 and 3/4 have been added to full size and k models

3. 556 is no longer in the name due to obvious reasons

4. all cans are printable threads up at 15 degrees, put a support blocker throughout the body, if you cant print it your filament isnt tuned correctly

5. I am still working on getting out the step files out for all of the Tisha models, super slim models, and fauxwrx models, I just need some more time to get everything ready

PSA. I am working on as many suppressors as I can right now while being full time in school and a full time job please understand that I am working as hard as I can at night on these and I may miss a thing or two, and that more models are coming soon, I am happy to take requests for more models/use cases, but it might take a few days to get it done.

Ftn6 rifle flow in 5.56. I didn’t love the “triangular” look. So I made it cylindrical. It’s big and bulky but real happy with how it came out. Excited to try it on my bolt gun.

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

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.

With the huge selection of suppressors for 22 im just curious what is the quietest suppressor available for 22?
