Update: Added extra-long version for use with stock fan.
This 40mm fan shroud and mounting bracket allows you to mount a fan to cool the print when printing with PLA. It mounts to the existing holes in the MakerFarm variant of the accessible extruder.
It is not compatible with the stock hot end cooling fan that comes with the MakerFarm kit because it uses the same mounting holes on the front of the extruder. It will fit with my improved hexagon cooling system:

and my Z-probe servo mount:

UPDATE: I added some photos of a sample print. The tree frog (http://www.thingiverse.com/thing:18479) is printed in PLA with a Hexagon .4mm nozzle, .2mm layer height.
UPDATE: I uploaded a new extra-long version of the fan shroud that allows you to bolt the mounting bracket over the stock 10mm-thick fan and still reach the nozzles.
