If you like this style, check out my Ender 3v2 Belt tensioner caps here.
Settings:
0.1 - 0.2 Layer-height
Supports on (i recommend painting them in Prusa Slicer only on the bigger bridge)
Painted the seam to be only in one line
Infill on 10%
If you want to print in multi-color, slice the model up and add color change in the layer slider, when the first layer of the text is visible.
The effect I have is an accident - I had a thick bolt on my extruder, which ruined the alignment and i had just basic knobs with no text, so i created a thin circle , which can be glued afterwards (good if you already printed the original ones).
But you can easily achieve that effect by just adding another color change in the slider.
