I use dnf sheets, extruded polygon and many diffs and intersections to build.\ Now I thinking about rounding edges.

The simple answer is that rounding is hard in the general case and that there is no good answer. Using minkowski() is the least bad answer, but is awkward (because it requires that you design the model under-sized so that the addition yields the right size) and difficult to control (because it will affect *every* surface and joint) and can be very slow.

Try the BOSL2 library. It provides many options to create chamfers, fillets and roundovers.
