I'm green with envy.  Very nice work!

I fixed it up using Rhino, but all I did was modify your piece, I didn't rework the entire thing. This is made evident by the yellow circles in the first panel which shows a perfect circle in relation to your design. Unless you have your solidoodle setup to make PERFECT circles I cannot imagine the small of a difference will matter. I hope this model helps. http://i.imgur.com/s9afsR5.png
your model is the dark blue one


dang, I can't submit files, so this is a link to it in Thingiverse. I can remove it once you have downloaded it if you want.

I somehow managed to get the image in twice.. sorry.
