Summary

This amazing lamp has a visible light bulb, which was just a little to bright for my taste so I designed a light diffuser which fits perfect.

It slights over the light bulb (use a "candle" shaped bulb) and fits in the top ring. Just a little twist and it hangs free from the light bulb.

I designed in two parts, a fitting part and a lamp part.
For the lamp part there are two versions: a one layer version to be used with white filament and a thick version for transparent filament.

One layer version:

The thickness is 0.4 mm. Remember to set the Wall Line Count to 1.

Thick version:
Print at 100% infill.

UPDATE September 10th 2025:
By request I included the Fusion 360 file

Good luck and let me know if this is working for you!
