After a lot of measuring, test prints, and revisions, the LED rail now has printed mounts and bar sections that work. That replaces the temporary metal ends.
The next step is cartridge spacing. Each short section has to aim its LEDs at the correct piano keys, and a few millimeters is enough to show up from the overhead camera. I am tuning one section at a time before committing to the full keyboard.
