To make a disk thrower, we decided to print a 3D printed wheel linked to a rotating motor on which we would put an elastic around to throw one by one the pile of 3D printed disks. To place  the disk on the path of the rotating motor we create some kind of L shape cardboard structure linked to a servomotor that would make a 45° rotation by pressing a button and it would then get back to its initial position. This way, the disk can be put one by one on the rotating motor path.
