Thanks to Lukáš OK1ECH and his excellent universal balun/unun box. I wanted to make a RF choke (or 1:1 unun), and since he posted the f3d file, it was easy to update to add two coax ports (SO-239 or similar).
I also changed it to M3 because I had an abundance of extra fasteners. I uploaded three files: a top (this is the same for both), and two base versions (both are M3) – one with his design, and one with two ports.
Follow all directions from the original version. Just substitute 4x M3x30 screws and 4x M3 nuts.
