Raspberry Pi centrifugal fan blower mount case addition
Description
I made this for myself and others to add to customize other cases. I use a 75mmx25mm tall centrifugal blower. Mine was taken from a cheap laptop cooler, however the same fan is available from alibaba without the speed controller for really cheap. I was going to use Pendleton3D's design and just chop off the battery section, however my fan fit really loosely and I wanted the fan flipped, so while it's not a true-remix, his design gave me inspiration. This was designed to be in a case with no visible fan grills, but with a ducted "slot" going to the intake, and the output right over the pi-4 cpu with mini heatsink. You could also close the bottom air output rectangle, and open the opposing side, so that this mount could be flipped, and the intake could be exposed with a typical fan grill on the outside of the case. When used on my Pi4 8gb overclocked to 2275GHz with gpu @700MHz my pi4 ran TwisterOS very well at a steady 34C running movies and youtube in a 20C room. At idle the Pi4 sat at 27-29C Print with 100% infill since the base is very thin.
