Cool Squeeze - Grip Fan
thingiverse
The human has finally succeeded in creating something truly remarkable: https://youtu.be/kWvck_Mz_q8 You can see the gear demo in action here: https://youtu.be/WQ8Kq8Ge7BE Take a look at the prototype and marvel at its ingenuity: https://youtu.be/FXmhC2h2yhk Does it actually work? Absolutely, it does! Will the breeze generated by this contraption cool you down more than the effort of cranking it will heat you up? That's still a mystery. This tech demo is an absolute blast to watch. To keep the device spinning smoothly, you'll need to carefully sand or rasp the inner surfaces where the wheels meet the axles. I also applied a layer of silicon lubricant for extra smooth operation. Held together with precision M3 screws, 10mm x 3.
