Center Vent Surrounds w/Fins

I have modified the standard Center Vent Surrounds to have a set of Fins that act as depth stops.
The make it easier to position the vents so that the correct amount of the vent extends through the skins.
These are the surrounds only! Click on the image to open a 3D .pdf version of the design.
