How to Print an Electric Motor

I started out by just wanting to make a very small drone. But I quickly realized that there was a limiting factor in just how small and light I could make any design: the motors. Even small motors are still discrete packages that have to be attached to all the other electronic and structural elements. So I began wondering if there was a way to merge these elements and save some mass. I drew inspiration from how some radio systems used antennas made from the copper traces on a printed circuit board (PCB).
