[Inner walls removal area]

Hi, I did my homework to the best of my knowledge and searched everywhere before posting to ask for help,

 

I have this part that has a very narrow area on top with a thin wall. From that layer height and after, I don't want cura to add inner lines, I just want the outer ones.

The reason is adding these inner walls is making my TPU part very rigid there, and I want it to be soft (even if that means it's empty inside)

 

I know I can play with the wall thickness, but that will change it for the whole model,

 

I was wondering if there is an option or a way around it similar to "minimum infill area" a defined area that smaller than this area cura won't add inner lines.

 

Thanks in Advance !
