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.

How to mod the case

1. Snap the template onto the top of the case
Tape the template down so it stays on Use a 3/32" drill bit to slowly drill out the small holes (Take the pi out before doing this!) Use a 1/8 " drill bit to slowly drill out the 4 screw holes Remove template Use flush shears to cut the plastic in between the small holes Push the center circle of plastic out Use a file to get off the rough bits Sand until the inside of the cutout is smooth (Do not sand the outside because it will damage the finish). Attach the fan Please note: I am not responsible for any damaged Pis and feelings. Try this at your own risk
