Rancilio Silvia RGB Led holder

Holder for 4 RGB Leds (my case WS2811) for the Rancilio Silvia espresso machine. 
You can use this with the CleverCoffee ESP32 modification for espresson machines. 

The OpenSCAD source file is included.

Attachment

Buy WS2811 LEDs with little PCBs attached, e.g. this chain or these modules:

Bend the LEDs 90 degree:

Push them into the holder (you need to push the PCBs further down than seen in the pic below. The pic is just for illustration):

Fix the LEDs in place (from the back) using e.g. transparent UV epoxy. Also put some from the front to seal off the module from an hot water steam.

Stick the lid on the back e.g. via superglue.

Stick the LED module to the Rancilio, next to the brew head. I used Tesa PowerStrips. They are removable and hold well.

Connect the modules to the ESP32 board (Gnd/5V/data).
