A while back I built some Kassutronics modules, and made some panels out of aluminium sheet for them.
They were looking a bit shonky, and Kassutronics aren’t selling direct to the UK anymore last time I looked (loving your work, Brexit).

So, I made some basic black FR4 panels for them. I’ve put the Kicad PCBNEW files and the gerbers here, in case you want to have some made yourself or use my work as a starting point to make your own panels.

I’ve got a handful of each left from my JLCPCB order, so if you want one, get in touch. If you can read this, I’ve still got them.
