Apparently the Feds never heard of the, Zip Gun. That's been around since before I was born and anyone can make one in their home workshop. It's far easier to do then with a 3D printer. Big difference is it isn't plastic so it would show up on a scanner.
In any case the plans for this are out there now, the cat's out of the bag.
