20-year-old Swiss student Kevin Thomas has created the next next-generation rubber band gun--not only 3D printed, but a gun that senses targets and auto-fires at them. His Rubber Band Sentry Gun, with files available for download on Thingiverse, can shoot 24 rubber bands in succession, and could be adapted to fire even more. Check out details on his inspiration and design in the full story: http://3dprint.com/86846/rubber-band-sentry-gun-3d/
