How to reproduce

When using Arachne, the outer wall of the balls sticking with each other with a small outward movement.

Classic does not have this problem.

I accidentally noticed this, cause I have printed this years ago with Cura and all good, the bearing prints I have done last couple days were sticking, investigate a lot on tolerance and finally found this.

My question is: is this a bug or it's just me not knowing how to set it up correctly?
I have tried lowering all things in Arachne options and the bump shrinks a bit, but still there

Actual results

balls were sticking together

Expected results

balls not sticking together

Project file & Debug log uploads
