For fan-shroud part, we recommend Prusament ASA / PC-Blend with default settings and 5mm brim if necessary. The fan-shroud STL file includes an inner support rim that needs to be removed after printing. It can be easily removed with needle-nose pliers, a knife, or flush cutters together with the brim. Otherwise, it will block most of the air from coming out. See the corresponding assembly manual chapter to see what the part should look like after removing the inner support. ASA, PC Blend, PA or even ABS, as well as other high-temperature materials are only suitable for experienced users, and being from different manufacturers, its properties may vary greatly. PLA or PET-G is a no-go for fan-shroud because of its low temperature resistance.

We recommend using black filament to print all MK3S+ extruder parts. If you want different colour, you can use it, but the FS-lever part should be definitely dark (black) and the other parts surrounding the IR-Sensor as well. In case you use any lighter colour for the FS-lever it might not trigger the sensor.
