Another LED Dimmer Control Box I have added LED strips to my Anet A8 (see pictures) : one on the extruder, and the other on the frame. There are three switches, to turn on the two LED strips, and possibly a third.

The controller module is : https://www.amazon.com/Controller-Module-3V-35V-Control-Switch/dp/B076KJYB64
