Global Site Rules
-
Content discussed within must be legal to discuss within the United States of America.
-
Do not manufacture regulated items illegally.
-
Do not spam.
-
Respect the rules of other instances. Other 3D-printing communities from other instances probably won't take kindly to what we do.
-
Do not disseminate direct download links to printable gun content unless it is a link to Odysee/LBRY or GunCAD Index. Accessories hosted on other sites (Thingiverse, Printables, etc.) are fine.
-
Before making a community for user-to-user sales or trades, reach out to @TheShittinator@forum.guncadindex.com -- we need to make sure those communities stay well-moderated.
Additionally, some pointers that aren't really site rules but you should probably still respect:
-
Being kind to your fellow man will typically yield better results than being a dickhead.
-
Talking in cryptic riddles may attract ridicule. Just say Odysee ffs.

FAQ
Q: I didn't get a verification email, what the fuck?
A: Use the "forgot password" form and it'll send you a new one. Also make sure you didn't typo your email when signing up -- if that happens, reach out to me and I can help.
Q: I subscribed to somewhere, but it says it's pending?
A: We're waiting for the server that community's on to give us the thumbs-up on your sub. Give it a minute or two, then if it's still like that, unsub and resub.
Q: Is there a good mobile app?
A: Yes, you want any app that supports Lemmy -- there are a lot of them out there. I'm personally trying out Eternity on Android. For iOS, people are liking mlem.
Q: I still need help, how can I contact you?
A: Join our Matrix Space and ask for help in General.
Q: Where should I go if this goes down? Do you have a reddit presence?
A: Official Reddit-side bunker: /r/3D2A. Who knows how long it'll last.
Let's talk about airguns, air rifles, air pistols, break barrels, springers, gas pistons, PCPs, CO2 cartridges, BBs, pellets, slugs, compressors, tanks, moderators, etc.
Maybe hunting with airguns, let's see how that goes.

I will post you here the WIKI from fosscad - just a little bit modificated. And you can open new threads too and give instructions! Dont ask here for help. For this we have other "communities"
A place to discuss various communications and radio technologies such as meshtastic, ATAK, and handheld radio networks.
Welcome to the hub for 3D printed drone enthusiasts! Share designs, builds, mods, and tips for FPV (First-Person View) quads, cinewhoops, and custom UAVs. Whether you're printing frames, mounts, or props for racing, freestyle, or aerial photography, discuss printers, filaments (PLA/TPU pros/cons), flight testing, and troubleshooting. No commercial spam—focus on open-source and DIY projects. Inspired by communities like FPV Drone Pilots and Oscar Liang's guides. Let's print and fly!

A community to discuss carrying concealed handguns. Please feel free to post your EDC, ask equipment questions, discuss ammo & technique, etc.
Rules:
- No politics - this forum is for people who are interested in CCW. We can add links in this sidebar to more politics-oriented forums if you want to create one & share it with the mods.
- Be civil - be polite to each other. No mean-spirited insults or attacks.
- Do not incite violence - discussions or defensive uses of firearms are fine. Suggesting that others commit illegal violent acts is not.
