I was able to slice with Arachne wall, but unable to upload because of the size. It did take my computer significant time to slice perhaps yours will be faster than mine. Remember to change the walls if you can. This print is only 1.5mm slightly thinner than normal.

Print at 100% infill with a layer height of 0.08mm with a base layer of 0.16mm
