Replicator 1 Adjustable Fan Duct

This is an adaptation of [Replicator Ducted Fans Clip-on to (a) cool Print](http://www.thingiverse.com/thing:40524) and [PLA Replicator Ducted Fan Clips Modded](http://www.thingiverse.com/thing:191297) to incorporate an idea from [40mm Fan Duct - Replicator 2X](http://www.thingiverse.com/thing:107080) This is for a Makerbot Replicator 1.

The basic idea is to use the print head cooling fan as a print cooler as well. By using some ducting and reversing the orientation of the print head cooling fan, the exhaust can be used to cool the print.

In this design there is no need to removed the duct when print cooling is not required - just rotate the selector so that air is exhausted out of the top instead of on the print. This has the added benefit of directing exhaust air upwards out of the printer and can reduce drafts that may affect your ABS prints.
