Description
Trimmed down the parent so that you can fit two on a Dual extruder Replicator.
It's a minor tweak of the parent, in Tinkercad at tinkercad.com/things/2lgOulFFXnr-dual-mk8-extruder-fan-duct-print-cooler.

Instructions
Print one each of Left and Right things, and follow the quite good instructions on the parent thing.

Thanks, laird (and apexio)! Here's hoping this is good for what ails me.
Just did the left side since I'm only printing with that extruder. I taped off the right side of the heat sink to minimize air loss that way.

All done printing my set of ducts... first sample print done, and the quality of the print does look better. :)

You only need the button-pressing-arm on the right extruder - you can delete the one on the left and save some plastic.

Very interesting approach. Looking forward to trying this out!
I am currently making a number of changes to my replicator in an effort to improve the quality of prints to somewhere near its advertising claims,.

After installation, the extruders are now off center by the width of the shroud. Also the extruders bind up on the extreme left X-axis position; we had to remove it as it was interfering with the calibration. How are these things corrected for?
I figured out a fix.
set your xHome offset to 140.
worked for me
Im having the same problem... Did you figure it out?
