I remixed the original case and thickened it enough to allow for the fan to be mounted inside. I also added a ribbon cable tab below the Pi's USB connections. With the added thickness, I was able to pull the ribbon cable out vertically which made it easier to bundle with the other cables coming out of the Pi's right side.
Print settings were fairly stock, but I did add supports for the cutouts because the PETG bridging across the rPi port openings wasn't as neat as when I originally printed my case in PLA.
The author remixed this model.
