I'm not having a lot of luck exporting what I'd like to be a smooth object as a .stl for printing. I get different combinations of gnarly areas where there a zillion triangles generated and visible oval rings on the flattened curves, but haven't found a magic combination of settings to export either really smooth curves, or evenly-distributed facets.

I did fix an area at the "peak" of the flattest curve, where lots of triangles converged, and gave me a small lumpy area. Putting a small flat on the "peak" seems to have kept MOI from using the point as an attractor.

However, with different settings, I still get either visible oval rings, small stray bulges, and/or oddly-place grooves. Very frustrating when you don't know what you are doing...

I've attached the model, if anyone wants to take a whack at good settings for printing it at high resolution on an FDM printer.
