If you're looking for an easy-to-print case and diffuser for your WS2812B 32x8 LED matrix panel, you're in luck. The case and diffuser have been designed to be printable on a common-sized print bed, and are split into separate parts for convenience. All parts either slide or click together, so there is no need for any additional materials.
The print has been desgined and optimized for layer heigh 0.16mm.
Case
The two parts of the case slide together to create a stable structure, but be sure to sand and test the fit carefully, as the tolerances are tight. Avoid forcing the parts together, as they are difficult to disassemble once assembled.
Diffuser
The diffuser is designed to click into the front of the case, but may also require sanding depending on your printer's tolerance. To achieve the best results, it's recommended that you print the diffuser with a layer height of 0.16. This will create two layers for the semi-transparent front of the diffuser, and ensure that the first layer is of high quality.
It's important to print the diffuser in a filament color that will allow the light to pass through, such as white.
Electronics
For my version, I used the following parts from aliexpress:
- WS2812B matrix 32x8
- ESP32
- USB-C breakout board
And flashed the ESP32 with WLED which you can find here:
Wiring:
Connect ground and 5V to USB-C breakout to the matrix right solder pads. Connect ground and 5V to the ESP from the matrix left solder pads.
Connect data pin from matrix to ESP D14 (or any other data pin you want). Remember to configure the pin in WLED.
