Just as SDL thing. I posted a similar shape a while ago. The edges 
looked *decent*, but only because I made the curves very small. The 
whole thing got me thinking about the odd parts of rounding a shape like 
this. There are no obvious solutions. Compromises have to be made, and I 
did some experiments to find what arrangement of compromises made the 
most attractive shape.

The corner bends are all perfectly cylindrical, like a CSG rounded cube, 
but the corners won't meet in a sphere like a cube's corners. The bends 
are all different radii, but the width of the bends is perfectly equal 
between edges. This is the best solution IMO (equal radii curves of 
different widths being another possibility), but it is possibly flawed. 
I've failed to think of a better way to join a concave curved edge with 
two convex curved edges of a smaller radius. What I've got here might be 
as good as that situation can possibly look, and, looking at some of the 
machined parts around here, looks like the same compromise made by some 
manufacturers and welders.

There *are* differences, however subtle, between this and what would 
come out of a modeler.
