I printed this Ender 3 display cover to block light, but when I used a transparent PETG filament, it was great at showing the display while dimming the light and redshifting it.

Printing this in ABS or PLA will produce a light blocking cover, while a transparent PETG will block some of the light, effectively dimming it while letting the display remain visible.

Enjoy!

If you have success producing a partially dimmed but visible screen cover with a PETG or other transparent filament, post in the comments! I'm curious how this part works with other filaments with respect to transparency.
