P.s. Just for a better explanation.

My method, or a similar one, is useful also because using it you can leave unaltered the topology of the original model,
without adding "fake" fillets only in order to make it more organic.

The model can remain the same and you can concentrate exclusively on its main look and aspect.

In this case and in all other similar cases, adding the fillets directly on the model is useless,
because they increase its complexity and modify its topology.

If all you need is FAKE filleting just for a much more natural look, the 3D-Coat method, or similar, I think is the way to go.
