Louvered fan cover

This is a derivative of so many Thingiverse things, I apologise if I miss crediting anyone. It is based on garycrowsellsr's fan guard (http://www.thingiverse.com/thing:26040) with an inspired addition prompted by nameless911 cardboard fan cover (http://www.thingiverse.com/thing:32660).
The cardboard cover is so efficient at redirecting the air away from the build platform that it means I could run my platform 10 degrees lower without the print edges lifting. But, being cardboard, it wasn't very robust or stylish.
So I added louvers to the plastic one to direct the air upwards, and that works fine.
The extension at the side is to trip the x axis microswitch on the Replicator.
Print it at a fine resolution - .15 works well - to make the edges solid enough to handle. They are very delicate and snap off easily until they are in place, but once on, they are out of harm's way.
The results are every bit as good as with the cardboard shield - 10 degrees lower build platform temperature (110 instead of 120) and no lifting of the edges of the print.
