these 3d printed guns are a joke anyway, 20x more expensive and 20x less strong. Why not just make your receivers out of sheet metal or a garden shovel:

crap shovel: $2
Romy sans-barrel AK kit: $200
Barrel blank: $30

It is more of an option for places where it is a lot harder to get things like parts kits and 80% receivers/frames. I agree though -- just about any home made zip gun would be preferable to that thing.
It is not so much the "thing" which is important here, but the idea and symbol it represents.
