16x16 LED matrix grid with diffuser and one-part frame

I'm determined to prevent the front from adhering to the frame, so I opt for printing the LED grid and the frame in a single seamless part. To achieve this unique design, I begin by printing the first three layers of the RGB grid with white filament. After completing these initial layers, I pause the print process and switch to black filament, carefully ensuring that every layer adheres perfectly. A flawless initial layer is essential for a successful build.
