3D printing working, safe-to-handle and durable guns is a pretty complicated technical problem. Don’t need to be a genius to figure out that making 100% plastic guns is asking for trouble. Tiny explosion = big plastic cracky.
Meanwhile, any monkey can bash together pieces of scrap metal and produce a durable gun that way. And that was a thing long, long before 3D printers existed.
It’s Ben Garrison! Dude can’t get an erection unless he labels every single goddamn thing. While being barely coherent. He’s been doing this for ages!
