The Arcus is a fully 3D printable rubber band Gatling gun that is capable of delivering 48 rubber bands downrange in mere seconds.

Unlike almost all of the other rubber band Gatling guns out there The Arcus uses the energy from the rubber bands that it is shooting to spin the barrels. The Arcus also features the arm mount system, meaning that to hold it you put your arm through the center and the barrels will spin around your arm. A cam system is used so that when you pull the trigger the barrels will start the rotation.

All of the parts are designed to snap together, no screws or glue will be required, because of this it can be taken apart and reassembled as many times as you want. The only other thing used in the assembly besides the printed parts is rubber bands. All of the parts are designed to be printed without any supports, and all the parts will fit on a print bed of 200mm X 200mm. This assembly is designed to work with #64 Rubber Bands with six Rubber Bands loaded onto each firing block.
