Official pi 4 case fan mod template

A template for adding a fan onto the official pi 4 case.

I really liked how the pi 4 official case snapped together with a satisfying snap but was disappointed that there was no easy way to add a fan to cool the hot pi. I remixed another design by minorcoma that let you drill holes into the cover but i wanted a full cutout for a 40mm fan. It snaps onto your top cover and lets you drill holes and remove the cover. See post printing for details. I just used the screws that came with the fan which I think are m3 screws. Takes just under 1 1/2 hours to print. I might make a version for a 30mm fan if people want me to.
