Nozzle Fan For Replicator 2x/CTC/Flashforge/Powerspec

I loved this nozzle cooler for my powerspec 3d pro. However with my aluminum carriages, the duct would hang lower than my nozzle.

To correct this I made the duct part thinner. In doing so I reduced air flow. To fix this i moved the fan back a little and tilted it.

This should be compatible with any replicator 2x clone; ctc, powerspec, flashforge ...etc

REV_1.0:
Change: Duct thinned, fan moved back;
Result: Airflow not as good as original, but not as thick as REV_2.0
REV_1.5:
Change: Duct thinned, fan moved back, fan tilted 70 degrees;
Result: Airflow improved from original
REV_2.0:
Change: Duct thinned, fan moved back further than REV_1.0;
Result: Airflow as good as the original.
