Lot of diffusers to reduce the points of light emitted by LED strips.
I use them on shelves and places where the LED strip is visible. I mainly use natural white PLA+ because it is the most balanced to allow light to pass through and diffuse it. The transparent is more for protection and elegance than for blurring.
These are installed between the LED strips and the IP68 clips:
So far I have not had a problem with heat since I use low density LED strips, but if you decide to use these diffusers with high density LED strips, take into account the melting temperature of the material you will print with so that there is no warping over time.
