What’s better than a regular rubber band gun? Maybe this fully 3D printed rubber band Gatling gun. The Arcus is capable of firing 48 rubber bands in seconds. It has parts that snap together without any screws or glue. It has an arm mounting system, so you can put your arm through the center with the barrels spinning around your arm.
