Support settings donut

I try to print a donut like this one

Material is PETG-CF. But the bottom side is not looking good because the support is too close and connected with the model.

I tried to increase z distance to 0.4mm and xy distance to 0.5mm but not good enough.

What support settings would you recommend for pattern, overhang, pattern spacing, angle.. for the bottom side of a donut printed with PETG-CF?

RE: Support settings donut

An option is to split the donut and print the flat parts on the build plate

In the project file above, I added 3 offset plugs, to help locate the parts for gluing

RE: Support settings donut

Anything CF is going to be a pain with overhangs. I usually prefer not to split my models but if you really need to use CF filament for some reason, I'd go that way. Or try slowing the print way down but even then I wouldn't be holding my breath.

It is necessary to print it from the bottom. Well the main issue is that the PETG-CF seems to shrink because of the support. Is is a good idea to decrease the density of the support and the support interface? Which settings?
