3D gun files can be easily downloaded and printed by anyone, creating untraceable firearms. In most states, this is completely legal. Stop Handgun Violence is working hard to ban 3D printed firearms by sending users to a microsite where users can contact their congressman or congresswoman to drive forward national legislative action. At the website, people can watch a video that dramatizes the danger of having people downloading blueprints of guns in their own living room without having background checks. “3D Tragedies” was a project created in partnership with production companies specialized in 3D and music.
