manual fan hand crank fan

This squeeze fan can indeed cool you down. It also makes your fingers stronger!

To be honest, all the squeeze fans on the market are just toys. They're fun for five minutes, but not very practical. The airflow is too weak, and your hand can get caught in the blades, making it impossible to hold. This is an upgraded, enlarged version that can really be used for cooling!

I also reduced the tolerances of the original design, making the fan less wobbly and the pins fit better.

If rotated too fast, the cap may separate from the housing as they are only held together by pins. Super glue can be used if necessary.

Please refer to the second photo for assembly instructions. There are two fan blades, and you can choose one. You may need to tap the pins into place with a mallet.
