HI,
I can tweak the shield to be more like the Karmann shape. The vent shapes are the direction that they are as it’s natural to read left-right, so your are used to that kind of lateral movement anyway. Standing on the driver’s side of the car, that’s the way they taper too. So they are heading in a natural reading direction.

I’ll knock up a variation or two later on. In the meantime, can we have a final decision on the name/initials for the group? I just picked one at random. Thanks.
