Fan brackets and ducts for i3
cults3d
The most effective way I found to cool PLA is the simplest ever: the two small 30° brackets I put on the back of my carriage, the ones the 60x60 fan is atteched on Other designs tested, here for your convenience, even complex ones, but I found it is not worth the effort to duct an axial fan: not enough pressure. My current setup (dual, direct+bowden) has two 40x40 fan on front (screwed on custom extruder and custom bowden adapters) and the 60x60 fan on back. Some FreeCAD sources attached for your own play. Enjoy!
