I recently published an antenna rotator made from 3D printed parts. We recently put it to an alternative use to slow wind a generator / transducer coil. The coil wire was very thin (ca. 0.05 mm diam.) and so very easy to break when winding by hand. We used the rotator to slow wind the coil ca. 1 turn every 9 seconds. A 2800 turn coil took about 7 hours. (Thanks to William Kim-Shoemaker) Ref. for 3D printed rotator: www.creative-science.org.uk/3D_rotator.html
