With this particular model, Prusaslicer is very optimistic about bridging and support generation:
- the right side (dark blue) has no support that could help with load-bearing
- the entire layer will be connected to those two lines
- more than 5cm long bridges
I don’t think this gcode will successfully print.
How do fix adjust the cura setting to generate a printable output?

Why are you printing this? Surface finish is super important to airflow in a design like this. Printing an overhang layer is not functionally adequate.
Mockup. Will be a few weeks before the real fan is delivered.
I would put the model in CAD and make it solid using a couple of booleans. FreeCAD can convert a mesh to a solid in the Part workbench.
Use support enforcers
Thanks. Is there also the option to rotate the pattern direction by 90° so it takes the short distances for bridges?
“fill angle” under infill settings.
Fill angle didn’t change this as Prusaslicer sees this as a bridge.
Bridges will be printed using the best direction PrusaSlicer can detect, so this setting does not affect them.

edit: just saw that there is a bridge angle setting that sets a fixed angle for every bridge.
