This is a cooling duct under development for the Makerbot Replicator 2X Dual-Head 3D Printer. (Check out the print quality before and after pics...purple before, black after)

*** DO NOT USE WITHOUT A FAN ***

DO NOT USE UNATTENDED, USE AT OWN RISK.

DESIGN UPDATED, BUT STILL A WORK IN PROGRESS. (23OCT13)

*** Added Rev3-higher flow version (25NOV13) ***

The purpose is to produce a cooling blanket of air across the print head/part to help produce a better quality finish on parts that have features that do not have enough cooling cycle time to solidify enough by the time the print head lays more material. This can result in a poor finish on certain features of a print.

This duct has been tested, and optimized for airflow so as to have a minimal negative impact on part adhesion to the plate, and maximize the flow to the extruded finish to provide a superior finish to parts. It works very well in our experience so far.

This duct will fit on the carriage, with a 40mmx4
