Pixel Art Matrix Display

This print requires a printer that can make a perfect first layer. As can be seen clearly, mine does not. On the right side of the panel, the light is diffused unevenly.

Print Instructions

• Choose a .2 or .4mm Nozzle 
• Print the first layer (diffusion layer) in white PLA (or any other white(diffusing) material)
• Print the remaining layers in black PLA (or any other light-blocking material)

Assembly

The back clamps must be bent to be put into place. These hold the front side tightly to the panel. M3 screws can be used to fix the print into place. One of the clamps provides a mounting place for a barrel plug socket.

The panel can driven using an ESP32 with the help of libraries, other solutions exist as well. My custom ESPHome Component makes setup and integration into Home Assistant very easy using ESPHome.
