Folger i3 Cooling Fan Mount

I modified the mount for this print cooling fan so that other accessories can also be attached (i.e. auto-leveling servo/sensor).
The fan duct itself hasn't been modified; it can be found at http://www.thingiverse.com/thing:1161013

The additional holes are also compatible with M3 screws (should fit tightly).

This part is meant to be used with a Folger Tech Prusa i3 (either acrylic or 2020 versions).
