Bubble Blowing Whirligig

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
