Vertical Wind Turbine VAWT

myminifactory

A beautiful wind turbine (Ø245mm x 800mm) designed specifically for balcony and low-wind-speed use. Built for my Ultimaker 2+ printer with a maximum build volume, large nozzle, and high print speed. You can easily print this on any big enough printer. I recommend using a large nozzle (0.6mm for "Flügel 8x.stl" with Vase Mode, 0.8mm for the rest). short video: https://youtu.be/4xszhV_X3DU ___ update 09/01/2017 Improved version of Flügel_8x.stl 19/01/2017: Uploaded a GCODE for the Wings (Flügel_8x.stl).
