Using German 3D printing website fabberhouse.de, Internet designs, and parts from his local hardware store, YouTube user Papierfliegerei created quite the contraption with a 3D printed gun that churns out paper airplanes, rapid-fire. Pointing out that the fun weapon just shows what one can do while tinkering around with 3D printers today, he shows off the fascinating functionality of the paper plane shooter, with the production occurring from underneath the 3D printed gun, rapidly folding the paper into the desired shape and then propelling it outward.
