Print without walls

[SinaFa 0]

I would like to print some parts (especially some squares) without any walls (/borders). How can I do that? 

I have these versions of Ultimaker Cura:

5.1.1

5.4.0

5.4.0-beta.1

5.6.0

5.7.0

5.7.0-beta.1

Thanks

If you're in the basic settings, click the Show Custom button:

Then change Walls > Wall Line Count to 0:

And now you have a print without walls:

But it shows an error when I select 0 walls!

The yellow colour of the input box is just a warning, not a flat out "can't do this" problem (that's when it turns red). It could be a combination of any or all of the settings listen in that error message. If you could sure the Cura project file (.3mf, in Cura go to File > Save Project) then we can have a look at all your settings to see what combination it might not agree with.

Thanks a lot

The problem was with skin settings (as shown in the yellow box)

Fortunately, I was able to solve it.
