Wind Turbine (Generator) 12v

thingiverse

Small DC wind generator which i designed myself, for producing electric power for charging phones, radios, LED light etc. Its designed to be rugged, weatherproof, cheap and reliable. With this design i hope to contribute countries and comunities which doesnt have basic electricity to light their homes !!!UPDATE!!! 4.12.2019- I uploaded picture of shaft couplers you need for propeller. Search it on ebay or aliexpress. You need one 4mm-8mm, but if you have some other coupler, im willing to give you custom stl, taylored only for your coupler :) !!!UPDATE!!! 9.14.2019- I allowed remixes on this turbine, so if anyone want to remix parts to fit smaller printing beds, go ahead! Just make sure you share with whole community :) Happy printing! !!!UPDATE!!! 17.10.2018- Since i got much suggestions for better, more aerodynamic flin design, i designed new flins, one with hole trough for putting 2mm steel wire trough center for better stiffnes and one without hole. New files are: "aerodynamic flin design with hole for wire.STL" "aerodynamic flin_design.STL" !!!UPDATE!!! 16.10.2018- since some advices taken from HACKADAY BLOG ( https://hackaday.com/2018/10/15/wind-turbine-pushes-limits-of-desktop-3d-printing/ ) i uploaded some of new files. Old files are still valid and absolutely usable, and new files are: "Housing without gearbox" - if someone wish to make this whole thing without nema17 gearbox, should print only this additional part. Its maked on that way to fit all standard nema 17 motors regardles amperage. SINCE NEMA17 WITHOUT GEARBOX IS HAVING SHAFT OF 5MM, YOU DONT NEED TO BUY 4-5MM SHAFT COUPLER (LOOK AT LINK DOWN IN DESCRIPTION!!! I also recomend 3 winged propeller with this motor, since it doesnt require much wind power and its lighter, but 6 winged will work just fine. "propeller with 3 wings (1,2,3)" are meant for making propeller with 3 wings. It use old wings or new one with holes for putting metal wire trough it for better streinght "hollow flin for propeller" PAUL from Hackaday recomend me to make hollow propeller for putting metal wire trough whole flin, which i did. It will fit 2mm metal wire (one for mig welding will work)
