Vertical Windmill Mk2 by miiiike - Thingiver

Bearing Mounts I printed 2 x Bearing Mounts with 2 x roller-blade bearings in each. I used 2xM8 nuts locked against each other above the top mount and below the bottom one to keep them in place. The holes are sized to suit a 10g screw with a 6mm washer. SCAD Don't be afraid of tinkering with this to get the blade shape / size you want.

Amazon.com : Solar Wind Spinner New Azure 75in Multi-Color .

The unit is of solid metallic construction. Unlike many other outdoor wind spinners with a single blade that spins in one direction, this spinner has a dual wind motion; the-tiers blades smoothly rotate in opposite directions on sealed bearings. The multi-colored spinning wind blades look graceful and offer gorgeous display of changing colors.
