I tried printing this replacement keyboard key that features a microphone, finally got a good consistency by turning the heat down a bit. However, the microphone was hard to see because it’s the same color/material as the body of the key.
So I hit the surface with my trusty magic marker, now the microphone really pops.
Still, it looks odd. I have ordered some black filament and plan to hit that with red marker, or maybe white appliance scratch repair paint if it hasn’t dried up. Stay tuned!
