RETIRED Spherical Wind Spinner

###RETIRED
**I'm retiring this because, generally, it doesn't spin well. It looks great and if you get the right wind, it spins like a demon - for a few seconds. I'm working on a new one that will spin well and hopefully look at least a little like this. So, have fun downloading and printing it if you want something that looks great and maybe spins a little when it feels like it. I'll update this thing with a link to the new one once I've published it.**

###Not to be Sold
**I'm sharing my files so that you can make them for yourselves or give them away as gifts. I hope you enjoy them. I do not authorize sale of my work by anyone. Please don't ask me.**

###Summary
This spinner is based on my [Festive Spiral Christmas Ornaments](https://www.thingiverse.com/thing:4689760).

UPDATE 1:

The new version is the same width, but taller, each blade is wider at the outside edge, the top and bottom are wider and simpler, and the blades are more vertical.

UPDATE 2:

By popular demand, I've created a version for dual-head printers. I don't have one myself, so I don't know how well it will work. If you try it, please let me know.

UPDATE 3:

I've added versions of design 2 (single and dual head) with sacrificial bridges at…
