after almost a whole year, I have finally managed to finish this raspberry pi case (thanks to stress and depression -_-" )
The case supports both the pi 3 and pi 4, but I have only made an io shield for the pi 3, since I really couldn't find any pi 4 STLs as an templete.
The case fits The Ice tower raspberry pi cooler, a 40mm fan (no Max hight), and front usb (with a little cable management bracket/shield to help with the wires to the fan and front usb, and protecting them agains the blades on the fan)
The case opens up like the real G3.
you also have the ability to run your cables through the opening on the back of the case if needed.
(There are many parts to print, and some of them requires a big printer like the Reality cr10, but a smaller simpler version will be made in the future.)
if you have any problems printing this, please let me know
