I created this adapter in order to install a 4020 part cooling fan on my Microswiss NG extruder. This will also relocate the fan to above the height of the extruder, allowing for the ingress of cooler air for the initial layers.
I have an Ender5 Plus which has a large heated bed. I was having part cooling problems with PETG on smaller pieces and this helped solve those issues.
The adapter uses three of the original screw holes on the NG shroud and has 2 additional 3mm mounting holes for the new fan. It is a simple and quick install.
I printed it in Petg with a 0.14 layer height
