This is a very simple cooling fan for the Makerfarm i3v, using a 40mm fan and next to nothing for mounting hardware. It's not pretty and it won't work as well as better tuned designs, but it doesn't get in the way of anything. I'm using a Hexagon and it's tuned for that height.

Remove the M3x16mm bolt from the side of the carriage, drill the hole a bit deeper so a M3x20mm will fit. The tab for the duct should have room to slide under and the bolt can be tightened down. The 40mm fan mounts with M3x10mm; the holes might need a bit of opening up depending on you printer. Or just use zip ties.
