VRML is already such a format :-)

This close-up of a laser diode package shows what blender is 
very good at -- render shapes as in a super natural way.

The shape was done with varicad and exported to blender as STL.
Note the artifacts on the supposedly smooth surfaces. There are
filters to get rid of these artifacts in the renders image. However,
in this case, the image looks better as it is.

When it comes to 3D construction, mesh formats like STL or VRML
won't help you much, though.

I'd strongly prefer to do 3D models with a full fledged 3D CAD
application. Preferably with the CAD app I use for the rest of my 
construction work. That's the benefit if pcb would communicate 
the full information of the layout to a free 3D CAD app. This app
would shoulder the tedious import/export to the complex formats 
of the real 3D CAD world -- IGES, STEP, DWG, ... 
Did I mention, that mesh formats are a one way road, when it
comes to construction? 
(Please tell me, that I don't need to make that point over and over 
again ;-)
