Here’s an excellent vertical-axis wind turbine (VAWT) project that caught our eye. The assembly video below helps to see how the piece is structured and how it functions. Created by Robotobi to interface with a work-in-progress low RPM Generator (at bottom).
A beautiful, modified Ugrinsky wind turbine. Intended for balcony and low windspeed use. Designed for Ultimaker 2 with Olsson block or UM2+ (max build volume, big nozzle, high printspeed).
