Summary This gun needs no supports, as it already comes with it's on that just snap off easy once finished. This gun comes with a comfortable grip handle to hold with your left hand, it also comes with a rubber band dispenser that you wrap a rubber band around the tiny pole on the inside of the front piece under the aiming part and then wrap more rubber bands around that rubber band around the pole, and unwrap them as you like. I've designed this gun to also use the least amount of filament possible, printing with 8.05 meters on my 7.5*7.5 inch heated bed, I spent around 20 hours designing this, and I hope you enjoy it! :) IMPORTANT: THIS MUST BE PRINTED WITH A BRIM!!
