The government is going to try and come after 3D printed guns as they can’t control them. They will look for a means of extorting money from those who have them. Parasites will create wealth so they will find ways of taking from others. Any kind of listens, permit, of background check is an extortion racket of the state. Don’t get their permission to be free.
