I have some LEDs on a circuit board and have created (in FreeCad) a 5mm thick overlay with holes for the LEDs. The LED currently shines through an outline. To diffuse the emitted light, I'd like to cover the existing 3d printed overlay with a mesh or screen effect. The LED would shine through when illuminated and be less harsh.
My current plan is to place a 0.1mm layer on top (in FreeCad), then have Cura make a 1 layer top surface. I've thought to edit the Gcode and change the Flow Rate to 50% or ? for the top layer.
Is there a way to tell Cura to space the lines ONLY in the top layer? I'm trying to avoid a laborious effort in FreeCad to create a mesh manually.
Possibly another approach?
Suggestions much appreciated.
Thanks,
Barry
