Hybrid annular fan duct
by destroyer2012, published
WARNING: This thing does get hot enough to warp if made out of PLA, but I believe that if made out of ABS it can be quite effective. Haven't tried that yet but it's on the todo list. Despite being flexible during printing the fan duct seems to hold up. We'll see how long until creep makes it useless.
UPDATE: Printed in ABS, actually handled the overhangs better than in PLA. The base warped a bit because my fan was going too fast so mounting it was very awkward. Managed to hack something together. Will test soon.
UPDATE2: Printed a hollow calibration pyramid (T:8757) using the new (bigger nozzle, made of ABS) fan duct, looks great! The best I've gotten yet. The next test is whether it will sag during a 10 hour print..
UPDATE3: been using the ABS version for three months now with no issues. It warped a bit initially because a portion of the nozzle touched my heater cartridge, but after mounting the heater cartridge properly it didnt warp further. Still works well!

This has been my experience with ABS as well. I don't know why some people say it's harder to print with ABS. Also, it may depend on what color you use. I have always used natural ABS.
I just printed one out of ABS for the first time, at 0.1mm layer thickness, I can't believe how much better surface finish it turned out compare to PLA. Maybe the extra temperature or different visco-elestic properties or both, I don't know! I've been putting off printing with ABS, first, because I didn't have a heated bed until recently, second, because of potentially noxious fumes from ABS. I think it is safe as long as it is in a ventilated area or in the garage overnight. Having withnessed the print quality, I'll be definitely printing more out of ABS, that's for sure!
