Pretty slick!
But out of curiosity are serial numbers allowed to be in plastic/polymer? The KG-9 has its serial number in the polymer frame and the ATF made them install a metal plate with the serial number on it for the KG-99. |

You fkrs in gd made me buy one of these and would not do it differently if I did it again. https://www.3dprintersonlinestore.com/tarantula-3d-printer-kit It is the diy type, think erector set, super fkn badass erector set. If you assemble it well, it will print ok out of the box. As you learn wtf is going on, you tune it up even more and they print just as well as the expensive ones. And now you know wtf is up, unlike the guys that bought the expensive ones from the get go. It is a excellent hobby that can actually produce useful parts. It's prob the best $250 I've ever spent on a hobby. You get your head around one of these things and it would be no trouble to build machine that will cut out 80% lowers in the basement. |

I wasn't aware the 3D printers put off CO prior to that. |

Except that it cost him $203, not $3, and it's not disposable because the serialized part is what will fail. If HPA passes then this becomes a really cool thread.

Damn dude, you should have just put a metal pipe over it and made that the serialized part. Then you can just reprint the mono core baffle stack whenever necessary without needing another stamp. That can't be against the spirit of the law because that's how lots of suppressor shops do it.
Great job though! |

They were prob doing something stupid. Can be easy to do though if you don't do the research before cranking the heat up, or don't keep an eye on the fkr. The more popular filaments don't give anything off, unless you burn it. The fancier filaments often need hotter temps. Many nozzles have teflon and you need to swap them out for the hotter stuff. |

The "printer" named in the orignial article does not exist and the closest thing to it was a laser cutter. The firechief and investigators stated that there was a 3D pringer in the residence and it may habe beem the cause. I was a stupid thing to say and a lazy way to possible close an investigation. No testing conducted on 3d printers has shown elevated levels of CO. Fumes and particles similar to laser printers I would put moneyou on gas appliance not working correctly. |

That is awesome. Even if it doesn't hold up long term, it's easily recreatable and can be a good stopgap option while waiting for the market to normalize if HPA passes.

Oh, and an umbrella insurance policy. Don't forget that either. R&D and umbrellas are required to suppress all the things. You don't know what the fuck you're doing. And I don't care if it "sounds" super quiet. You need the $6000 test equipment to prove it's quiet. That's called R&D. Come back after you've bought the umbrella. |
