CTC, Flashforge Gehäuselüfter, Chassis Fan Mount CBiker Remix

I liked the Design of the original http://www.thingiverse.com/thing:597231 from CBiker very much, but had some problems on the right side with my x-axis stepper motor (exactly with the holder for my cable guide) and also I wanted to have a replaceable solution, so I can change the fans with plexiglas when I print with ABS.
Please look at the picture how to mount it.

Should work with any 120mm fan
