Simple fan guard (80, 92, 120, 140 mm)

I couldn't find an 80 mm fan guard that was plain and fast to print, so I decided to design my own guard set. Included are versions for case fans with 80, 92, 120 and 140 mm outer width (71.5, 82.5, 105 and 125 mm hole center distance). The mounting holes' diameter is 5 mm, so there may be a bit of resistance when fixing them.
The mounting holes are a bit raised on one side to increase the distance between the blades/cables and the guard.
 
 
Important note: **Only the 80 mm guard is tested!
