The advent of 3D printing has been hailed as a watershed moment for democratizing everything from medical instruments to prosthesis. It’s changing the way we think about manufacturing, the way we heal, and apparently, the way we dick around in our free time.

Designed and engineered by Matthew Davis, a member of the 3D printing community Instructables, this complicated gatling gun fits over your arm to like Samus’ hand canon and fires off up to 48 rubber bands in just seconds. One of the most impressive parts of this whole design is that once you print all of the pieces they can snap-assembled without screws, nails, or glue. Oh, and did we mention it is free? [Purchase]
