I really liked the Klipperscreen case made/shared by Ganjew420, but I have a Raspberry Pi 5, which I did get to fit (here), but not as well as I was hoping, unless I cut some parts out. But even then, it doesn't work right because the power button necessitates drilling a hole in the outer closure, and the port for an audio jack in the original case is pointless and there's only one port in the case for a PiCam ribbon cable (the RPi 5 can have 2).
I came across Adafruits RPi 5 case models, and decided I like that a lot more. It fits perfectly, and if you use the Official Raspberry Pi 5 Active Cooler, you can easily take the top cover off without needing to unplug the fan.
The author remixed this model.
I simply took the little mounting tabs off of the bottom of the RPI case, and added them to the RPi 5 case made by Adafruit.
