Wind Turbine

*Update: New top with better air flow and better motor mount. New rear wing. Upgraded gear for better performance and less noise while working. I recommend that you print the gears in PETG or ABS because of hight working temperature. New Column for outdoor camping by sticking in the grass.*
This is a simple but effective wind turbine. It is capable of generating 1 Volt with a mild breeze
You are able to see a video of the assembly here: https://www.youtube.com/watch?v=LQb85M5BKAs
You will need:
five 3x15mm screws
two 3x12mm screws
five 4x15x10mm bearings
one 4x19x13mm bearing
I used the motor that opens the lid of an disc reader, but you can find it here: https://www.ebay.com/itm/MABUCHI-RF-300EH-1D390-DVD-CD-Drive-5-9V-DC-Motor-Drive-Model-Making-Hobbyist-/272771785647
