I use binder clips to hold my models in place, and have twice now managed to print a model that ran the head over the clips.
It would be great if I could specify that the bed has a margin of ~n~ MM. I know this reduces bed volume overall, but using the binder clips does that anyway.
As an advanced implementation, maybe make specific allowances for “intrusions” like binder clips? A non-square clip area? Or having the margin only be ~x~ MM high?
