If you think there is still not enough wind, go get an electrical fan please. A hand fan can only do so much!
Update 2022/08/26:
Uploaded bigger blade design with everything labeled "XL”. The new blade is 78% larger than the original blade in turns of area, hence requiring a sturdier crank, body, and handle, etc.
Print turbine with support or no support depending on your comfort with 30deg overhangs.
For kid's toy, I recommend the original turbine 1c with the outer ring, but it doesn't provide enough wind for the increasingly hot global warming!
Original design 2021:
Let's just admit it, all of the squeeze fans available are just toys. They are fun to play around for 5 minutes, but cannot really be used functionally. The wind is too little, the hand gets caught in the blades, and nowhere to grab. This is an upgraded larger version where you can actually use it to cool down!
I also narrowed down the tolerances of the original design to make the fan less wobbly, and the pins to fit more snug.
If spinning too fast, the cover may separate from the case since they are just held together by pins. Use superglue if necessary.
Please see the 2nd photo for instructions for putting together. There are 2 fan blades, choose whichever one you prefer. You may need to use a mallet to knock the pins into place.
Print with PETG, ABS, or similarly strong material. DO NOT print in PLA!!
Squeeze Fan Ruggedized! (Not a solution to an electric fan!)
