I have made this layout to another project, but you get the gerber and send to seeedstudio if you like. Board is 150x200 mm and snap-ins are 35 mm Ø. I have made it single sided because I plan on etching it myself when I get around to it.

Feel free to elaborate about your concern. The layout is very simple - basically just 5 cobber bars like it is often done with screw mount capacitors (see e.g. Pass Labs' larger models).

The loop area in between the flow and return traces will emit interference.
If you have a two layer board you can superimpose the flow and return one above the other.
A single layer board should keep the flow and return traces close together.

So basically, identical challenges as seen in p2p mounting.

I'm more concerned about the fields from the transformers and I am also considering using four 2mH air-coils for CLC. It is difficult to find a way to place them without having magnetic fields all over the place.
