Other Issues:(Fkn 500 character limit) Set walls to 2, inner wall thickness to .6 mm, and reduce infil to 10%. 15% max if you don’t want any flex. 25% gyroid is extremely dense infill. Overkill, especially with 4 walls. Seam painting should rarely be used since the seam will tend to wander left to right in your painted region. You need to thin the painted area down to a few pixels to get it to play nice. Use “back” or “aligned” seam instead. Seam looks really sloppy on this print due to that wandering ridge.
