Has anyone seen or heard of a Fallout style combat rifle in the works? I’m a huge nerd and fallout is one of my favorite games. A replica combat rifle would be awesome to have especially bc I have a rifleman build in fallout 76

Hello! If youre reading this and have a FMK 91C please hit me up. I need some reference photos of the frame. Kits for these are pretty cheap and I'd like to hop on Fusion and get one designed and printed. Please feel free to message me if you have one. TIA

The Ark @fosscad.io Mantis frame keeps detaching from supports.

Iv printed the scarab v2 totally fine but this keeps either disconnecting from the supports at the front or rear. Polymaker pla pro 220/65 80mm/s top z distance .26. I have it orientated at a 45° like the scarab v2 but this has less surface area with the build plate than the scarab v2. How did yall print it/ orient it?
The Ark @fosscad.io The pla pro is good for weapons like the fgc 9 mk2?

The Ark @fosscad.io ASA frame failure
Originally posted by u/Ok-Blood8662 at 2025-06-30T21:50:55Z
Was hoping I got good enough layer adhesion here, and I may have, but cracks formed at the pin holes.
Fortunately did not have this happen while firing. I noticed the cracks when inspecting the gun at my desk, flexed it, and it completely snapped.
Figured I would share as an example to others. Filament choice is super important in 3D2A. Be careful.

Modified files to fit in Hoffman AR-9 Super Lower. Original files fit mil-spec AR-15 lower just fine. Both function check good after minor break in.

I see the kits for 40s and 9s, but no 45s. Is there a beta or did someone make one already?
The Ark @fosscad.io Update to the Chiqtana (Delayed blowback 9mm fully DIY)
Originally posted by u/Admirable_Scholar_36 at 2025-06-30T19:54:59Z
Sorry for lack of updates, finished my degree. After making a few barrels I changed the trunnion mount, rather than using pins, you can use flat bar, and file the receiving channel on the barrel to fit them. Again, this uses no existing gun parts, and you can ECM the barrel. You will need a drill press to making the screw holes in the receiver plates, but I am also working on jigs with drill bushings and printed housings to make the drilling process repeatable and accurate. Feel free to ask any questions.

I saw a whole ago you could upload an STL to them and they'd serialize and print the thing and ship it to an FFL. I guess that's not a thing anymore on the website. Is it still a possibility to do or are there any other places offering the same service?

Hey squad - My KAK barrel for a Nylaug build is passing on both Go and No-go gauges. Is this normal for the KAK Nylaug builds?

The Ark @fosscad.io Roboprop / Cop-Outo9
Originally posted by u/Dude_I_got_a_DWAVE at 2025-06-30T18:32:57Z
Im developing an Auto9 prop for my old 92S. A 0.75” OD steel tube will inserted into the hole and overlap the barrel with 1mm clearance. I’ll grind a lead-in and ports prior to press fit/gluing/(pinning?) it in place. The steel tube will extend ~10mm from the end of the prop assembly. The prop will be held in place by a cross screw inside the trigger guard…..and a shoulder bolt screwed into the tip of the aluminum recoil spring guide, tapped for M4. The shoulder bolt head will prevent the prop from rotating downward during cycling. Also considering putting a cross bolt through the front web of the trigger guard.
The Ark @fosscad.io Mac 11 issues

Hello, I just wanted to start this post glazing u/Pfunk117 for introducing the wackmack, one of only functioning super safe mac11 builds I have found in the sea. I have tossed hundreds of dollars into other super safe mac11 DB9 derivatives all for them not to work and destroy my barrel.
My upper is a VMAC 11".
Now for my main issue, I was using my wackmack as normal on the range and dumped 120 rounds through it for 3 days. Keep in mind, the only range ammo I used when running this gun was Remington and Blazer FMJ's. I let one of my friends try out my weapon on the range and he loaded some Winchester Full Metal Jacket Flat Nose target rounds through my gun and it exploded leaving this.

It could need to be a little less spring.
