Slicer random overhang issue

Hey guys,

I'm working on a Recession Ruger remix to accept OEM Ruger mags and have a working slide stop. Thanks uberclay for all your groundwork on it!

When I go to slice, Orca is putting a break about half way up the magwell, parallel to the build plate. Regardless of the print orientation, it seems to always put a break there, and I can't figure out why or how to fix it.

Can anyone please help? Thanks

Note be blue line which is an overhang.

A view just above the issue layer.

The red is a \"top layer\".

When I change the orientation, the same line appears, but it's at a different angle, parallel to the build plate again.

I covered up some surface geometry, but this cut goes all the way through the mag well, so I don't think that's the issue.

Unicorn filament? Tullomer

On YouTube the 3D Printing Nerd just released a video about this new filament, tullomer. It really sounds too good to be true. If this lives up to the hype, this will be amazing stuff!

The straight mags do it for me.

It drives me nuts that even though the upper, lower, and front pic rails are all the same filament they all look like they're different colors due to print orientation. However, it runs like a sewing machine and it's my current favorite PCC.

First (functional) 3D2A Build - DB Alloy

Finally got my first real 3D2A build mostly complete. My print settings (mostly supports) need some further tuning, but I'd say it's too bad. Once I get my safety assembly & mag spring in, I'll be taking it to the range!

Saved the last little bit with the jank setup on pic 3&4. Support cracked, so I shoved a pen in there while it was printing and it seemed to come out OK lol.

For a paint job, I'm feeling a desert night camo, maybe black multicam. Any input from the peanut gallery?

I plan on trying to find a way to get an IR illuminator & tape switch mounting solution, there's not a lot of rail-estate, so I have to get creative. If anyone has any experience with trying to make a DB Alloy into an NV setup, please let me know, I'd love to hear some input!

Huge shoutout to u/Kilo_Axtual for the parts kit, he's a real OG. Fair priced, quick shipping, and a nice fella. (Not sponsored he's just a good dude).

Looking for P365 files

Does anyone know of any p365 sailing? Looking to do a build, something a little (actually a lot smaller) than the g26. Thanks in advance.

If ya know... ya know. Are any internal parts printable with resin?

I started my first NAG and was wondering if any internal parts are printable in resin? I know my x1c can make quality prints but nothing beats resin for precision and quality. There's alot of resins out there now but most tend to be brittle. Any recommendations or is it just a dumb idea?

diy maxim stock and brace

i designed a diy and printable maxim stock and brace all the original hardware fits but haven't done the diy rods yet to confirm they work i made jigs for the cuts and also have a printable version that uses smaller steel rods for reinfocement but im unsure if itll be rigid enough. its not on the 🌊 yet but if anyone is interested i may start a beta room on element to check if its working. the price is looking to be about 45 for 1 or 80+shipping for all the hardware.

10 inch 3dp90 barrel

Is there somewhere I can go to get a shorter barrel for my 3dp90? I've got a 12.5 inch barrel in mine, but would like something shorter. Mainly to have it look closer to a real P90 (end of the barrel flush with the front of the gun).

I could probably go to a gunsmith and get the barrel cut and re-threaded, but I feel like that might be more expensive than buying a shorter barrel (if they exist at all).

FGC-9 Brass insert failure - test firing at range first time…

After 54 rounds, two of the brass inserts pulled out and the bolt didn’t close. Questions - has anyone gone up to 4mm inserts and bolts? I read of someone using the brass #6 wood inserts and screwing them in with a soldering iron chisel tip. Worst case, I might redesign the upper to take thru bolts on the two side bolts and then maybe insert two brass inserts on the top hole? Just seeing if anyone else encountered this, and what their solutions were. It’s a left handed FGC - reverse the upper, ejector, and bolt carrier and good to go. Before the failure, the gun shot flawlessly, and with a cheapo red dot, dialed in with a cheapo laser bore sight, we blasted out the bullseye out of the gate.
