Print at 100% infill with a layer height of 0.08mm with a base layer of 0.16mm (Feel free to add brim if you have adhesion issues),

I would check the flush options (if you have AMS).For me 0.25 multiplier is good enough.

You can resize it but don t change the height.Z height must be 1.80mm

Also i have 1 AMS so i paused the print at the mid of red layer and changed the other spools.
