Stevens Wind Turbine

thingiverse

This turbine design fits a 3mm shaft directly onto a motor, generating 4 volts of power while weighing just 19 grams. Easy and fast printing takes under 2 hours to complete. Have fun! Print Settings Rafts: None at all. Supports: Absolutely not needed. Infill: Set it to 10 percent density. Notes: This piece prints directly without rafts, supports or any additional parts. Once the print is complete, lay the components flat on a surface and you're ready to assemble them. If you want to improve the turbine's efficiency, attach one of the wings to a curved surface, apply heat to shape it, let it cool down completely, and you'll be all set!
