That's a good suggestion, thank you for sharing!
I have tried to fill the cotton buds with white acrylic paint the other day, but it looked a bit messy. I could try with graphite, although I am realising more and more that I think that I don't like to add plastic to the fretboard, at least for this build.
I guess is something about the fretless neck. It's so minimal that I want to add as little as possible.
I have also considered just to drill a 1mm hole, and leave it, hollow.
It looks great in daytime, but unfortunately in the evening with dim lights the holes lose any contrast, especially the ones looking down towards the 9, 12, 15, 17 fret.. On the unlined fretless I need some sort of reference position, not to mention the dirt that might accumulate over time.
