So i hade a bit of problem with the print fan shroud starting to get soft and dropping down on the right side (that is unsupported) when i was running print with huges first layers so the print fan was not on for a long time.
I grabed the STL from Prusa GitHub and added a little support on the right side.
Hope it helps you as well!
Print with support on the right for the "hook" (See Picture or use Gcode)
Only PETG, PLA will just melt.
