  Lol. Printing frames is very easy and requires no more computer proficiency or knowledge than anyone under 40 already has.
  Edit: it can all be done on a $99 printer with a $20 roll of filament.
context: This is a really good thing.
  I own guns and I built a Glock knockoff.  It's stupid easy, and all the parts for a functional gun were mailed to my house.  Took less than an hour to do it all. >

  It's a largely useless thing.  3D printing exists and will make perfectly serviceable receivers for guns. >
  
  3D printing a handgun is currently a lot more involved than mail ordering a Polymer 80 kit and removing a few bits of plastic.  Of course this ruling won’t completely prevent illegal possession of handguns, but it will reduce distribution to people who are prohibited from possessing firearms.  If 3D printing becomes cheap and easy enough for anybody to do it, then that’s a different issue to address.
