E14 lampshade.

0.2mm layerheight or higher, randomized z-hop to generate the dots (these are not a printfailure/air) to add a bit structure to diffuse the light.

Holes for ventilation, print in PETG.

Use normal filament to get a softer effect, transparent filaments for more brightness. Play around with printspeed, nozzle temp and cooling to achieve more opaque or transparent effect.
