4-channel mosfet standoff

I bought the following 4 channel MOSFET board: AliExpress link, and wanted to pimp my 3D printer with RGB LED's, because that's what all the cool kids are into ;) (according to Thomas Sanladerer).

I designed this stand off plate for the bottom of my IKEA Lack housing. I created something in karnschi style.

To enable RGB LED's in Marlin, just enable #define RGB_LED and set the pin. I used pin 4, 5 and 6 since these are PWM pins. (the lights can be dimmed)

#define RGB_LED 
//#define RGBW_LED

#if ENABLED(RGB_LED) || ENABLED(RGBW_LED)
  #define RGB_LED_R_PIN 6
  #define RGB_LED_G_PIN 5
  #define RGB_LED_B_PIN 4
  #define RGB_LED_W_PIN -1
#endif
