The file 'Ender 3 Hotend Noctua 4020 Fan 3D Printer Model' is (SLDPRT,STL) file type, size is 40.4MB.
A slightly modified version of NoComms Noctua 4020 cover.
The fan mounting holes were made to go through the entire front face to allow for oversized screws (I was using 25mm m3 screws)
The gap around the heater block was increased so that when using a silicon sock, the printed part does not touch it and melt. (The original print I think is fine for the stock heater block but the Microswiss FMH came with one that is a bit bigger than the stock heaterblock)
The mounting holes for the nozzle's blower fan are moved up by about 1.5mm on the Modified blower part to allow for using a printed nozzle blower that has a longer neck. If you want to use the stock blower part, use the stock option.
