Hi Codiac, my original shroud installed at a slight angle, drooping to the Pinda side
i printed your v4 model and it mounted the same... at an angle
to correct this I crudely clipped about 1mm off the fan insertion opening, on the straight edge below the fan
this enabled your design to mount better on my printer...
there was no adjustment available in the fan mounting and removing material from the fan its self, was not an option.
