Hi Marco, well it looks pretty good. You have to do a pretty detailed reflection analysis to see any problems. (screenshots from Rhino Zebra analysis)

Some things are pieces that are tangent continuous but not curvature continuous like this:





So the question is - is that good enough for manufacturing? Maybe yes for some things and maybe no for others.

There are also corner spots where it's not quite G1 though:





Those are probably bigger issues.

So no doubt it's useful for a whole lot of cases but finicky industrial designers are going to be upset about those little details.
