The file 'Sovol SV06 Plus Back Mounted Cooling Fan Duct 3D Printer Model' is (stl) file type, size is 1.8MB.
The x-carriage on the SV06 plus must be a little thicker than the SV06. Its the same duct by rogerquin (https://www.thingiverse.com/thing:5959054) but with the clip slightly extended to fit my machine.
