I'm crap at modeling, but I had a project where I'm using these cute little matrix displays to show some automation states. 

Diffuser + backplate are a friction fit. Print diffuser with a filament that allows decent light transmission. 

Attach case to stand with CA glue. Clip on stand is a little brittle, so use care when routing USB cord. Designed so nothing needs supports to print. 

Parts:

• Waveshare ESP32-S3 Matrix
• USB-C to USB-C cable with 90º  (any will work I'm sure, just what I bought)
