Summary

I've had a functional 3D printer for about a month, and this is my first complex construction. I’m entering it in the “Catch the Wind” challenge.

The rotor turns nicely in a light to moderate breeze. The planetary gears provide a 3:1 reduction to the 12 bubble wands dipping into the reservoir, and helps prevent violent splashing in a strong breeze. The fact that the wands go in the opposite direction as the blades gives a nice esthetic.

Additional materials include:

4mm Corrugated plastic sheet for the blades and body. After the next election, several hectares of the material should be readily available.
One Inch 10-24 nuts and bolts: Five are used to hold the rotor assembly together.
One inch 4-40 nuts and bolts: Three are used to mount the planetary gears.
1/4-inch dowel to form the axel.
brads or other small nails. These are pushed through the holes in the mounting brackets and through the corrugated plastic. They do a good job of securing the printed parts to the sheet.
cyanoacrylate or other glue to lock the 4-40 nuts, secure the sun gear to the dowel, and secure the wands in the holes around the outside of the ring gear.
BB's for the ball bearings

It took me some time to convince the printer to work, but the project comes together pretty quickly after that, which is fortunate, since the last part came off 6 hours before the deadline for the
