I have not found a suitable modification to the excellent print fan shroud created by RH_Dreambox: https://www.thingiverse.com/thing:4376765

to suit the Mk3S+ (the latest Prusa extruder design marked R6).

There is one solution prepared by goldbird3: https://www.printables.com/pl/model/199028-prusa-mk3s-rhd-fan-shroud-duct-revc

but it uses the original fan mounting point on the Prusa extruder cover, which forced to add a connector for fan mounted with new shroud. This looks bad in my opinion.

So I checked other solutions and finally decided to remix the original R6 version of the Prusa extruder cover: https://www.printables.com/pl/model/57217-i3-mk3s-printable-parts

to use the fan bracket developed by wavexx: https://www.thingiverse.com/thing:4172720 https://www.printables.com/pl/model/144797-mk3s-nozzle-rhd-rev-c-remixed

and the fan shroud from goldbird3 (which he modified based on the C version: https://www.thingiverse.com/thing:4376765

rather than the CS version: https://www.thingiverse.com/thing:4124587

in my experience the C version has better internal geometry).

This approach was necessary in order not to change the shroud geometry designed by RH_Dreambox and to be able to use the Mk3S+ upgrade without additional fan mounting parts, proposed by wavexx.
