For somethings a mold is just superior

This is just a video taking advantage of the "3d printer" craze. I could shove anything into a shotgun shell and it would be just as effective at punching a hole through a plastic bottle.
A cheaper solution would be to roll up $100 bills until they were the right diameter and shoot that down the barrel vs buying a 3d printer to "make bullets."
It would be interesting if they built an effective 3d printed gun, that shot a "tround" style projectile. That might have the chance to work, or have some meaningful usefulness.
