The Elegoo Centauri Carbon pillar with diffuser/stand, uploaded by Jesusfreak. It is printed using transparent PETG material, and you can also choose white to soften the light when it's too bright.

If your LED strip lights can't be firmly attached, these accessories might solve the problem and keep them in place. The clips on the pillar might be a bit too narrow for both the diffuser and the LED strip lights. I routed the LED strip lights outside the clips, which still ensured their secure fixation.
