The design came from Wikipedia (please contribute there)
One 'tip' would be to take the main coil core off the mount, and print only that. The holes can be used to mount directly to a board, as well as the pasthrough for the wires. Spend some time smoothing or even polishing this piece. I don't know that it's needed, but it may help?
