Made a quick PCB design for the Nipkow disk.

I planned to do it with aluminium externally at first, but they won't drill 0.4mm holes, so PCB was the next sane option.
The disk will be mounted with a mounting hub directly on the motor axis.
I could have gone with a record and hand drill, but this way is easier, and I don't want another abandoned project due to lack of free time.
