Slicer: setting local parameters?
I am using CURA as a slicer and not the current version so my question might sound strange.
I would like to know if it exists a slicer that allows local parameters vs global parameters for the 3D printing.
I have a structure which I want 3D print with a thread. Today the solution I use to have enough material to actually make the thread is to set the "shell thickness" at a high value (let's say 3mm). It means that the overall thickness of the shell will be 3mm, no matter where I am on my part. But, to save time and PLA, I would like to have a shell thickness of, let's say, 1mm everywhere but 3mm where I have to do my thread.
If not clear let me know because I realize it is kind of difficult to explain for me (I am not english native ;-)
