The Arcus, by Instructables user Matthew Davis, is basically a fully 3D-printed rubber band Gatling gun capable of firing 48 rubber bands in mere seconds. Unlike similar creations, this one uses the energy from shooting rubber bands to spin the barrels. It also features an arm mount system, similar to the one Samus wears in Metriod, and a cam system that activates the barrels when the trigger is pulled. The parts are all designed to snap together, which means no screws or glue will be required. Click here to view the first image in this week’s funny demotivational posters gallery.
