fan mount with a go pro hinge

My Go pro fan mount.
I needed a way to mount a small fan behind a network patch panel. I just wanted some air circulation back there. I have this go pro mount so I combined the 2 designs. I made a go pro mount for a 30mm fan and a 40mm fan.
The fans measure 30X30X10 and 40X40X10.
To bolt the 30mm fan to the mount you will need (2) 3mm X 16mm socket head screws and (2) 3mm nuts.
To bolt the 40mm fan to the mount you will need (2) 3mm X 12mm socket head screws and (2) 3mm nuts. There is a pocket in the 40mm fan for the socket head to fit into so it takes a shorter screw. If you turn the fan around and mount it the other way then you will need (2) 3mm X 16mm screws.
You will need (1) 8-32 X ¾ screw and (1) 8-32 nut for the go pro hinge.
All of the screw holes are slightly undersized. Just run a screw through by hand and they will open up. Both parts are on a common brim for an easy print. But it does require some careful clean up post print. You need to remove the brim from the go p
