Matthew Davis’ Arcus is a 3D printable rubber band gatling gun. Its unorthodox appearance is more than just for show. Unlike most rubber band guns, the Arcus uses the energy from the rubber bands being shot out to rotate the barrels and continue the barrage.
The always resourceful MrGear shows us how to transform a pencil, a matchstick, a 9-volt battery, and a few other bits and bobs into a tiny weapon, capable of firing a nasty little dart. It’s probably not deadly, but it sure could cause injury, so be careful if you try this at home.
“…it’s 400 times over the most dangerous rating imposed by the FDA. So without further ado let’s play with this thing.” A statement that no one should ever say, but YouTuber styropyro utters it as if he was talking about a NERF dart. This thing would be right at home in Fallout 4.
