Hey Aaron, thanks! I'll keep an eye on your thread

 

If you pull those vents you'd better have some Krazy glue handy because they are extremely brittle and I'd be surprised if you get them out in less than 3 pieces. As for printing,it's been tried and they are too flimsy. Silicone or steel casting mold is the only way to go. The one I've received this far is made from aviation grade plastic used on aircraft glare shields and he's elongated the installation clips for a better fit.

 

That's exactly the advice of your fellow Brit, the movie actor Dudley Moore! This is a scene from the movie "Crazy People":



In the above scene, Dudley Moore, the salesman, is explaining to Paul Reiser, the buyer, that this ad tells Jaguar owners to have their cars washed and polished by hand, preferably by a woman with a soft touch, in order to keep the paint like new.

I know it's an old movie, but some things never change.
