Recently I took some time to make my CNC router operational again (perhaps I'll post about this in the future), and what better way to make the case than mill it out of wood :-). I had some black alder stock left over from our sauna renovation, which was of suitable thickness and width. So I fired up the CAD and started drawing.

I then cut the piece out on the CNC router, where everything went smoothly. The tooling left a 3mm round over in the inside corners, which - in order to fit the PCB - I had to remove manually with a chisel.
