Pla prints with large supported area has Bad surface finish

Well, as the title implies, i am trying to print this part out of PLA. (forshape ecoPLA)

I have an enclosure and a filament dryer, and the moisture is about 44% in both of them.

I tried changing the top contact Z distance (from 0.25 to 0.1 mm), but this only made them harder to remove.

Does anybody have an idea on how i could get better surface finish ?

Thanks for your answers.

Did the printer generate supports?

I try to make safe suggestions,You should understand the context and ensure you are happy that they are safe before attempting to apply my suggestions, what you do, is YOUR responsibility. Location Halifax UK

Also, i made sure to check and the supports stayed attached to the build plate and there were no layer shifts whatsoever

It would probably print better tilted at 45°, you will still need support.

Some designs are very difficult. I would print in two parts ( Centre disk and the rest with key lugs) press fit - and glue if needed
