This is a simple light diffusing cover designed to fit Waveshare's “ESP32-S3-Matrix” board.
I designed and printed it with "Eryone" brand white PLA, but I imagine any slightly-translucent filament would work. Clear filament would probably also work, but you'd have to rough-up the flat side to make it diffuse the light.
I designed it to friction-fit onto the board, but because the part is quite small, the fit will be highly dependent on your printer and settings. If your part doesn't fit, please just reprint it rather than forcing it, otherwise you could damage your board.
