Weird zigzag infill lines on thin wall

[DimaGorbenko 0]

Hi,

Please, take a look at the image attached below:

 

You may seen what in the model I have thin wall and after googling and playing with settings I still have some questions:

1) Why the thin wall is printed by zigzag lines on left and right side instead of straight line ? I've marked these problems with white color on the image.

2) Why the thin wall is showed as "infill" ? I'm using the term "wall" because only after checking "Print thin walls" setting that wall was printed. Otherwise it's ignored by Cura because it's too thin.

 

Cura 3.6.0

 

Also attaching the project on this model.

 

Thanks,

Dima
