3D PRINTER ENCLOSURE 120MM FAN VENT

I am currently building a enclosure for my Lulzbot Taz 5, with the help from MrMcGuire's Taz enclosure files. I Ordered Two 120mm pc fans, and realized my temperature will drop if i have Two 120mm pc fans. So i designed 2 big fan vents. Now i can be able to close and open the vents. With some trimming with an Xacto knife, you will have a nice fan vent. I made two different styles, one that you can snap and join, and one you can join with a M4x12mm hex round head bolt.
