Replicator 2X Fan Duct

ATTN: Work-In-Progress!! I'm still working out some details in the model. Also this design may not blow enough air to be very effective. Tubeaxial fans can move a lot of air (CFM) but they aren't very good at generating pressure (as in through a nozzle). I'm working on a second design using a blower-style fan which generates about 6x the pressure, which may work better.

This thing allows you to add the third cooling fan to a Replicator 2X. The third fan cools the freshly extruded plastic, which is critical for successful PLA printing.

It cools only the right-side nozzle. If you want to cool the left side, just mirror the part before printing. I may add a mirrored version soon.

This part requires no modifications to the Replicator itself. However, you will need to snip off one of the mounting ears on each of the fan grilles or the screws may not be long enough to thread into the stepper motors.

I added a wire to the unused fan output on the factory board and ran it
