Oh yeah, rubber band wars at the office got a level up with this 3D printed rubber band sentry gun. Forget the old days of finger flicking rubber ordinance at your cubicle foe. This gun, created by 20-year-old Kevin Thomas of Switzerland, is constructed from 3D printed parts, an Arduino Mega and servo-motors to control motion. It can find targets and fire upon them automatically using software from Project Sentry Gun.
His final gun design, which was first inspired by the Automatic Rubber Band Blaster, is available for download on Thingiverse. So now you can defend your cubicle while on an away mission to the breakroom.
Check out more images and video demo after the break.
