Different Layer heights for specific parts of an object using modifiers - possible?

Hi All,

I'm trying to get a smoother finish on only 2 sections of a screw-top container. The yellow sections represent the modifiers I added for the sections I would like to have smaller layer heights compared to the rest of the container.

My hope is to reduce the layer height in just these 2 sections for a smoother finish. Is this possible and if so, could someone please explain how I would do this?

Many thanks in advance!

Gunter

The area of the thread is easy. You can either right-click and add a height range modifier, then specify the range in which you'd like a different layer height.
 

Or you can use the Variable Layer Height button on the toolbar:

Th area on the right is a different story. To my knowledge, there's no way to change layer height restricted to the area of a modifier, only across the whole object.

Thank you, here's the stl file:

I'd like the lower section to have fuzzy skin and the threaded section the smallest layer height.

Many thanks in advance!

Hi Gunther
the key ring loop is a bit of a problem
I added height range modifier to give fine layers for the thread and a modifier cylinder to give fuzzy skin below the thread, (bypassing the keyring loop)

but as Foxrun3D cays, changing the layer height on the keyring loop is difficult, and to be honest, probably not a good idea, Stefan at CNC Kitchen did some tests which suggested  that thin layers increase the probability of the model breaking at a layerline

I like Joan's edits.

I would add that if this is your design, I would make a couple of changes.

For an object this size, the threads feel a lot smaller than they need to be. I would increase the thickness of the threads, so that you don't really have to change the layer height. 

Second, the keyring loop has an overhang that would require supports. Another option is to smoothly extend it down so no supports are needed:
