I'm delighted how well this has come out.

Printed in dark grey PLA, 0.4 nozzle, 0.2 layer height, 20% infill on my shiny new Ender 3 Pro.
I started with the lite flow panel, but changed all the lettering to 1mm deep 'engraved'. Sanded it smooth, then filled the letters with Tamiya X-2 gloss white acrylic paint. After that I (carefully) sanded again to remove the excess.
I was amazed how crisp and sharp the text printed 😎
