This is a lowpoly version of vertical windmills. Easy to print in vasemode.

I even made a threefold version wich spins easier in low wind and looks better with dualcolor-filament.

The centre has a diameter of 20mm so you can use a simple plantstick as axle.

print in vasemode with standardsettings. best with 0.8mm nozzle but even works good with 0,4mm nozzle.
