Outerline is not printed in one go

[Simplify3Dnew]

Hi, i am having trouble to find a setting where i can change that the inner line is printed in one go.
as you can see in this picture it prints the holder as a separate peace but i thing then the strength is not high enough for it.

maybe someone knows where i can change this behaviour

I see this behavior only when there is a tiny gap between the two pieces.

You could try using the "Separate Connected Surfaces" option on the Mesh dropdown menu.

If it is what I think it is, you'll end up with multiple entries in the model list.....but the slicer will slice perfectly!

If you do get multiple models, watch out if you try to move the part on the bed....or centre and align....without first merging the separate parts of the model in the list into a group.
