Cooling/Ventilation for Valve Index.

No disassembly needed!

You will need some sealing or 2 soft pads on each side of the fan to make it stay in place.
I use a 30x30x10mm fan, and it fits "like-a-glove" no need for glue/screw.
The USB-connector I use fits but 2-3mm more and it wouldn't anymore.

Apologizes for the rough print on the sample.
I haven't done enough testing to ensure it will do any good :)

This is my first upload, and even my first ".stl export" so please let me know if there is anything I should think of next time.
