Nice builds!
I just built a second pedalboard, because I needed more stuff for another band, and I needed more outlets so I figured I'll make more of these, but I wanted it to be more compact.
This is the PCB I made, using a smaller form factor DC-DC converter (Aimtec AM1SS-1209S-NZ), which is basically the same one I used before, but in thinner, standing format. I drew up a small simple PCB and ordered a prototype from JLCPCB:
With this I was able to cut down the size of it, to fit it under the board easily!
I know it looks a bit wonky, lots of superglue and plastic casing... cause I realized it late that I should plan it using PCB mounted DC jacks, but hey, that's where we all learn from our mistakes.
The thing works fine, I omitted the inductor after the converter - just used a 2R2 resistor and no problems, it is dead quiet with my pedals.
