However, the screw hole for the mounting screw that passes through this piece, the fan, the and the bracket that attaches to the ducted fan, appears to be placed too far to the right (as viewed from the front). It's not possible to mount this piece back on the overall assembly because the screw will not line up with the ducted fan bracket when it is placed over the "right half" of the extruder assembly. EIther that, or this thing is supposed to have a much tighter fit than I think it does.
I assume that it was Guillaume who designed this piece, maybe he can fix it. Or maybe I'll have to have a go at trying to design my own.
