Cooling Fan Mount for Raspberry Pi 3 and 4

thingiverse

<h3>Universal Raspberry Pi 3(B) & Pi 4(B) Cooling Fan Mount</h3> Whoa, this took some time to design and avoid all the components on both boards, but this cooling fan mount will effectively cool both a Pi3 and Pi4 if needed! (Also looks really unique!) **Only 20 minutes** are required to print, and it features three fixings that can be securely screwed onto the Pi board. Fresh air is directed over the hottest parts of the board, specifically the CPU, memory, USB, and power chips. Make sure the airflow of the fan is blowing downwards for optimal cooling performance! **The fan must be 5-volt and 30x30 mm in size (any height supported);** * The positive (+) lead connects to pin 2 * The negative (-) lead connects to pin 6 * ... of the GPIO connector **Printing Instructions** When printing, ensure that the bed sticks well and is level. I printed with an Ender 3 at a 0.3mm layer height. **Coming Soon...** I'm publishing a really nice set of Raspberry Pi cases very soon that can adapt to any size of Raspberry Pi fan (even the huge LED ones!) ... I am confident that you'll love them!
