I got it fabbed at JLCPCB, though later realized that the stock panel had counterbores on its mounting holes so the screws would be flush. JLC can't do that, so I'm going to see if I can DIY that with the drill press at my local hackerspace before I get the next run made.

I also accidentally got them made out of PCBs of the wrong thickness, and I forgot that the CPU module and wireless antennas would be in the top half so there's a full copper layer underneath that lettering which won't be great for wireless reception. Ah well, you live and learn :)
