regardless of your stance on them, the fact of the matter is that any major 3d file hoster (Thingiverse, Printables. Cults, etc.) are not the place to get the files to print a firearm. a lot of firearms are found across the Internet and are relatively easy to find
they're perfectly legal where I live and I just think they're neat, but I'll have to destroy them if/when I move to where I want to go
that was my initial thought too, but then I remembered that if may not be so obvious to those who aren't like-minded like that. it's still good to share with friends and family who might not know about it
