Case prints without supports, I used PETG with 3 perimeters (0.6mm nozzle) for mine.
The holes for all the plugs are left intentionally as very big opening to help air flow through the case to stop the pi from overheating.
The Screen from AliExpress comes with the distance holders and used screws included.
Please note that for me the screen rotation after installing the drivers as described by the vendor did not work:

But the instructions in this link did work nicely to both rotate the display and the touchscreen:

(I used the Rotate 270°, for landscape with the USB C coming from the top)
