I wanted to make a completely 3D printed helicopter that flies, without having to fiddle with wire for the rotary joints or plastic/tissue for the wings' surface.
Inspired by seeing science Olympiad helicopters on YouTube.
You do have to use a rubber band, and (optionally) some lubricant for the rotary joint.
