I hacked up Adrienadr's RPi 3 case to mount behind the angled LCD on my Ender 3 S1. This is useful with Klipper and https://github.com/RobRobM/DWIN_T5UIC1_LCD_E3S1.
I used tree supports for the holes and protruding tab, but the the supports turned to spaghetti and those parts printed ok, so maybe you don't really need supports.
Note that this lid doesn't have a cutout for the 4-pin PoE connector because I already trimmed those pins, but you can search Thingiverse for 559858 to browse alternate lids.
