I have in my bedroom a nice Koogeek smart plug of multiple plugs, each one has a very bright green LED that annoys me during nights.

I created this very simple and quick solution to diffuse these LEDs and sleep without having to unplug all the whole system! You will need a translucent or not colored filament to diffuse the light properly.

The design it's parametric which means that you only have to open the Freecad file and choose your desired measures for yout case.

I've used some hot glue to attach it without damaging the original product but you can use any solution that you want!
