You can go on the internet and download a CAD model for just about anything, especially open source.
My son's high-school has several of the 3D printers too.
I guess my question is - its not just access to 3D printers, there are commerical ones and industrial ones. You also need to proper materials I think. Can a commercial printer really create a pistol/bullets and it be reliable & workable?
I lean more towards worrying about real firearms vs 3D printed ones right now.
