About this 3D model

A small ballista for shooting cans or other targets. Follower, hook, and arrow are printed with supports, but the supports on the hook and follower are minimal, and the arrow needs a raft as well. Infill can be around 15-20%. After printing, insert the hook piece into the body so that the hook faces forward. All that needs added is two rubber bands through the follower, through themselves, and looped around the corresponding end of the body's arms.
