This is a simple fume extractor designed to house a single 120mm PC case fan. It is modeled specifically for the Arctic F12 which is usually less than $8 via Amazon Prime.
There is no hardware required to assemble the extractor. I designed it so that the "Cover" will slide over the "Main Body" snugly. If desired, the optional "Intake Cone" can be placed onto the top of the "Cover" to concentrate the area of extraction down to a 2" x .75" area. The "Intake Cone" has been uploaded as both one-piece and two-piece versions.
If you do decide to use hardware, I have designed-in four 4mm holes at all four corners (on 105mm offsets) in the "Main Body" and "Cover" to allow for the installation of screws or bolts to secure the "Main Body", "Cover", and fan into one unit.
There is a .5" hole in both the "Main Body" and "Cover" to allow for the power wires to be fed through and out the back.
