DJI Mini (2) Cooling Pad

thingiverse

This useful when you just power ON the Mini (2) without flying. Without this, Mini will start to get hot and eventually will rise an overheat error because it relays on air from propellers for cooling It is fold-able and print in place, if in doubt you'll be able to unfold and you have a large printer, print the extended variant instead. DJI Mini has no active cooling. The cooling relies on air coming from propellers during the flight time. When is not flying, and powered ON, like FW update or filming, it will overheat, raising the overheat error.. This will address those issues, uses a 40x40x20 Fan, thus providing the active cooling, even when Mini is not flying. I used a 12V 1W fan, powered from USB, as it is silent yet powerful enough to keep Mini cool, but because draws too little current 0.01 A @ 5V the DJI power bank will stop current after 1 minute. A 5 V fan can be used instead, though can be much nosier, provides better cooling and can be powered from DJI power bank as it draws 0.07A @5V Also you will need a USB cable to power the FAN. There is a room for some extra circuitry, if you want to use a boost up from 5V to 9..12V with a potentiomerter thus allowing variable speed for fan. It is fold-able, Two variants provided, if your printer cannot handle tolerances well, you can print extended variant directly, you can try fold it, but do not try too hard :) To secure the fan in case you can put one or two pieces of filament in corner(s), then press on the fan frame, do not press on blades. https://youtu.be/5U6xC7z3wQk The print video is here https://youtu.be/d29X9L59exE
