DJI mini 3 pro cooler

thingiverse

This is the cooler for the mini 3 pro. It cools it while downloading videos, upgrading firmware, or playing with the settings. I'm using the fan I have laying around. The square hole for the fan is 20x20mm. You can modify this thing to your needs. It is snug fit to the m3p. Although it has a small gap all around the air flow from the fan is more than enough to compensate for the air loss. It is printed back side (where the hole for usb c cable is) down, so it uses minimal supports.
