Stackable Upgradeable Vertical Axis Wind Turbine

This designed was inspired by the wind turbines in the Dyson Sphere Program video game. It uses partly 3D printed bearings and is meant for decorative purposes, although it can be attached to a magnetic rotor to generate a modest amount of power. The design is stackable and allows for later upgrades, with each added segment twisting by 10° in order to complete a triple helix. The Darrieus blades have small holes in the edges to allow the use of bits of 1.75mm filament as dowels to strengthen the bond between segments.
