Portable Wind Powered USB Charger

I made an original one, but the motor I used was alot smaller in diameter. So I made a few adjustments to the hole fot the motor. Made 19mm and a 21 mm shaft, so the motor is kept tight in place.

Motor and USB-port are not generating any power yet, but with some trial and error I'll hope to make it work upcoming few days. But if you have any suggestions, please let me know.
