Light Diffuser for Aliexpress Crystal Light/LED Stand

Not sure if this already exists, but I got given an crystal + LED stand for Christmas and these are the same stands sold on Aliexpress. 

The LED is far too bright and can't be dimmed, I made this very simple diffuser to dim down the intensity of the LED which has the bonus of changing the light colour with whatever colour filament you use. I printed this at 0.2mm layer height and using tree supports.
