The Raspberry Pi 5 having been released, I remixed this model : https://www.printables.com/fr/model/44218-7-touchscreen-case-for-raspberry-pi-4-internal-fan to make it compatible with the Pi 5.

The zip contains the top and bottom of the case. 

For other “display case”, “fan” and “stand” files, refer to the original Pi 4 model, they are the same.
