Print everything upside down and mirror the left duct to get the right duct.
To get optimal results, different types of prints require different ducts (Desi Quintans' http://www.desiquintans.com/coolingtests2, http://www.desiquintans.com/coolingtests). Wider ducts are better at preventing warping while narrow ones are better for small parts , overhangs, bridge. This design allows you to easily swap out ducts with slide & snap or use a combination of wide and narrow ducts as suggested in the experiments.
How to design your own
Simple!! Just redraw the spline curves in the attached "duct_only.f3d." (modify sketches named "curves_standard" and "opening_standard." See https://youtu.be/ctuSp7M95Bo)
If you design an awesome duct or a cool remix for a sensor, let me know and I'll post links to your things here!
Remember to come back and post what you've printed as Make.
It's good for the designer and the community (that means you)!
