Hand Powered Fan
This is a hand powered fan. It spins using a finger tapping motion.
It was created in Tinkercad and printed in ABS on a Flashforge Creator Pro 3D Printer.
The fins are only small so it doesn't move a huge amount of air. But it's a fun desk toy and can produce a little bit of cooling.
I'm hoping to create a V2 in the future with larger fins and gears to spin the fan even faster.

The idea of a tapping motion to spin the fan is based on wooden fans created by Youtube user noho91
