I made this shroud to replace the original on my Ultimaker Original Plus. With this fanshroud you can use alternative (Ultimaker 2 compatible) extruder nozzles. With the original the shroud would hit the print bed.
I know there's many like it... but this is mine... Mostly because the others for instance use spacers between the shroud and connecting parts... this one can be assembled using only the ultimaker nuts and bolts I already had. The shroud is exactly the same thickness as the fan... so those bolts can be used to keep it in place.
Make sure your heater block is rotated the same way as mine!
Print it standing on the side facing the extruder to print without support.
