About this model

My version of a semi-circular part cooling fan duct for the Anet A6. As well as the fan duct itself, you will need to print and install the 'Part fan bracket' to hold the cooling fan in the correct position relative to the hotend nozzle. I changed the position of the fan mounting holes on this bracket slightly in order to centralise the cooling duct on the nozzle. I also added a slotted hole in the bracket so that you can level the fan duct properly (mine was at a slight angle). I have also added a simple X-axis cable strain relief point to the bracket. No supports are required for these parts.
