This is an awesome system for WLED. This is the case for it. It is specifically modelled for:

Controller

• AZDelivery NodeMCU ESP8266: amazon.de
• 2x USB-C Connector Female with screwholes: Aliexpress
• 4 Big Screws
• 4 small screws
• 24AWG Cables Aliexpress

I have also created a schematic in the image gallery.

LED Strip

It is meant to be connected to a WS2812B led strip with a custom USB-C connector, and there is also a schematic for that in the image gallery. You can connect a USB-C Power supply, which is super simple.

• USB-C Male Connector Aliexpress
• WS2812B Led Strip Aliexpress
  I HAVE NOT PRINTED THIS, AND CANNOT CONFIRM THAT IT WORKS
