The file 'Ender 6 Gantry Fan Mount 3D Printer Model' is (f3d,stl) file type, size is 204.2KB.
This model was created to keep a Raspberry Pi and Buck Converter cool with a NF-A4x10 that were used to power an Ender 6 running Klipper. There is no reason the fan couldn't be mounted elsewhere on the gantry as per the design.
