120mm Fan Mount for 5.25 bay with a insert to add a dust filter

120 mm Fan mount that fits in front of 3x 5.25 bay drives in your pc.

I placed netting between the fan mount and the insert to create a dust and bug filter.

May need some sanding, based on the indents of your computer cage.

Update:
Created a V3 146mm wide version for the guys who want to insert the whole mount within the drive bay. [untested]
