I just upgraded from a Raspberry Pi Zero 2w to a Pi 4 B and needed a case.
I choose thing 3852672, mainly because of the rail mount and cooling fan.
I just thought I needed a cover to help keep the wires from my filament sensor
attached and to clean up the GPIO opening.
Here's my remedy to both problems. It stands off the case 1.5 mm so it doesn't
over pinch the wires.
Thanks for the original case! Printed easy and the fit was perfect!
