3D printers
Printable AR-15 magazines and lower receivers for 3D printers.
And while you’re at it, a 3D printable car.
Someone else is working on magazines too.

Let’s get realistic, no one is going to shoot an AR with an ABS receiver, but this is an important milestone.
Instead of printing a lower receiver, one could use one of the open-source CNC mills to craft a lower receiver out of foam, except maybe 12% bigger all around. That foam core could be used in “lost foam” casting, which is so low-tech that you don’t even need to have any special casting sand or foundry mold-making skills.
You know, I always applaud those people who go into refugee camps to tried to make these people’s lives better. Other people help out by designing evaporative refrigerators or efficient twig burning stoves or solar cookers or ways to purify water. No one ever seems to address the root cause though.
What happens when open source tech and a little persistence gives everyone on the planet effective means of self-defense through an item made of materials so everyday and ubiquitous that no government can ever hope to ban them?

I’d shoot one!
I’d tie it to a tree or something and pull the trigger with a string (a long, long string), but I’d shoot it.
AR lowers are low-stress parts. Now, a plastic AR upper, not a chance.
