Extruder Cooling Duct for ABS
thingiverse
We know that for ABS, in most cases, it is recommended to turn off the cooling fan in the slicer. However, in Ender 5 and 3, when doing this, we also turned off the electronics fan. And this is dangerous. So I made this piece so that we keep the fans on, but deflecting the wind from the two hotend fans, since the main fan also impairs the use of ABS. This prevents us from having to physically change the electrical wires to keep electronics fan on, as I have seen in videos out there. Tested on Ender 5, but should work for Ender 3. Remix from https://www.thingiverse.com/thing:3255518 (this is good for increasing ventilation, in the case of PLA, for example.) I recommend printing in ABS or PETG, 100% infill. The piece is very close to the hotend, so... v1 v2 v3 - Smaller and better (Remix from https://www.thingiverse.com/thing:2726365, this is good for abs and pla, but with the danger of the electronics fan off)
