Filleting a corner with 3 radii is non-trivial. No single ball radius can stay tangent to all faces at once, and the corner must be filled with a general n-sided blend, typically a Gregory patch that matches tangency along every bounding arc. Example: a 5 mm, 3 mm, and 2 mm corner has three fillet surfaces of different sizes meeting at mismatched heights, so the filler surface is a numerically-solved patch, not a primitive.
Have you checked your STL Export Quality? It comes down to surface deviation (distance) and normal deviation (angle). Curved regions benefit from more triangles and print smoother. Lower settings are fine on flat, prismatic parts; but on a cylinder, sphere, or fillet it leaves coarse facets the slicer reproduces as visible flats or banding.

Today I'm testing @Convert2Step: a new STL to STEP tool currently in private beta.
It's one of the first standalone web-tools of its kind I've seen, but I'm certain it won't be the last.
A few weeks back I was bitchin and moanin about the fact that current mesh to solid... 🧵
