Fan Duct i3mini Combo
thingiverse
This is a project through which I add a second fan that blows only the material and the main one remains only to cool the extruder. My mini has an additional fan slot that allows you to add and control such a fan through cura. All you need to do is add an additional double cable from the bottom to the second fan and remove the protective metal plate on one side of the extruder. Then you need to adjust the PID settings in the software. For stable operation with the new fan I use the following settings: P 100 I 2.00 D 130
