1) The most important new feature in Cura version 5 is that it handles thin walls better. So make sure you have Cura 5
2) make sure "print thin walls" is checked. This allows you to print walls twice as thin versus if you don't check that.
3) Look at "horizontal expansion". If you set that to 0.2mm it should expand each side of a "wall" by 0.2mm to make all walls at least 0.4mm and that should be enough that you get something printable.
4) Fans, propellers I have found to be the most difficult thing to 3d print because of the support issue combined with how delicate each blade is. I hope you have a dual printer that can print water soluble support.
6) You can print down to 75% of a nozzle size without much (any?) degradation in quality. So for a 0.4mm nozzle consider setting line width to 0.3mm. Also then you can set horizontal expansion quite a bit smaller as well but eventually the part is too delicate.
Often getting started is the most difficult part of any process. A good start sets you up for success and saves you time and energy that could be spent elsewhere. That is why we have a onboarding course ready for
