Official pi 4 case fan mod template

prusaprinters

<p>A template for adding a fan onto the official pi 4 case.</p> <p>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.</p> <h3> Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Creality</p> <p><p class="detail-setting printer"><strong>Printer: </strong> <div><p>Ender 5</p></div><strong>Rafts:</strong></p> <p>Doesn't Matter</p> <p><p class="detail-setting supports"><strong>Supports: </strong> <div><p>No</p></div><strong>Resolution:</strong></p> <p>0.2</p> <p><p class="detail-setting infill"><strong>Infill: </strong> <div><p>20%</p></div><br/> <strong>Filament:</strong><br/> [</p> <h3>](http://www.amazon.com/s?url=search-alias&amp;field-keywords=Hatchbox+PLA&amp;tag=thingiverse09-20)[ Hatchbox](https://www.amazon.com/s?k=hatchbox&amp;linkCode=ll2&amp;tag=thingiverse09-20&amp;linkId=f798b0df863f056fa470f03a65697ff4&amp;language=en_US&amp;ref_=as_li_ss_tl) PLA Gray Post-Printing</h3> <p><strong>How to mod the case</strong></p> <p><div><ol><li>Snap the template onto the top of the case</li> 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).
