Yeah, I know exactly what you mean :-/

Okay.  Then it's strictly the tessellation process itself.  I believe there
are a couple of tolerance parameters (linear and angular) which you can set
when you do the STL export.  The smaller you make those, the closer you'll
get to the true cylindrical shapes.  At the same time, the output files
become much bigger (because there are N^3/2 more little polygons), and your
geometry initialization will take longer.

Good luck!
