I didn't know STL's were that bad! It's just a file from Thingiverse
Well there are two issues here:
1. Stl is only planar triangular facet representation of curved surfaces - this is OK for 3D Printing, but not design.
2. For it's intended purpose stl is fine, but in my experience most of the designs posted on sites like Thingiverse were rubbish before they were exported as stl. The users seem to have little education and experience. Kind of hard to put lipstick on a pig.

If you zoom in and rotate around this area - you will see an issue I suspect the original designer did not recognize.
