The Internet last month treated us to a custom-built, adult-sized Nerf gun that swapped out the soft darts for plungers stuffed inside pool noodles. Now, we've got another childhood favorite that's been injected with steroids - the rubber band gun.
Matthew Davis designed and 3D printed the Arcus, a fully automatic Gatling gun capable of firing off 48 rubber bands in just a few seconds. This sure beats the old fashioned method of flinging bands with your fingers although I'm sure it takes a good bit of time to reload the monster.
Davis has even uploaded the details on how to make your own rubber band shooter at home... so long as you have a 3D printer, of course.
