120mm Knife Valve

Couldn't find a knife valve, and was tired of trying fancy apertures and other nonsense. See attached.

The Knife valve should bolt in line with a 120mm fan. It also should work with my Qidi Tech Vent Kit: http://www.thingiverse.com/thing:2008891.

Have fun!

I'll post pictures once I have it printed.

Also do note, you should be able to print this without supports. The bolt holes will be a little rough, and the inside won't be beautiful - but who is going to see it anyways? Finishing
