Drew this up in CAD and printed this for a friend:
It's a nose-cone (aka: "spinner") for an RC plane. His previous one didn't support a 3-blade-prop so he had me make this for him.
I was impressed with how easily support material was removed, and how it was able to print from a knifes-edge on some of the fins.
One thing I learned from printing very circular shapes like this one is that you really need to bump-up the STL quality (I think that's referred to "increasing the poly-count") in order to reduce the visible straights that are used to create the curve. If you look really close you can see all of those little straights in the part... and that was printed at a pretty high resolution.
Very true, I already used angle tolerances of 3 degrees for some curved objects…

I use 3 degree angle in Designspark and Spaceclaim as well.. Takes longer to render but results are way better.
