Is there a way to keep the inner mesh and deleting the outer mesh after extracting a shell?

[Lizzieoh]

Hello!

Is there a way to delete the outer mesh of the extracted mesh and keep the inner mesh to create somewhat of a “offset” mesh?
I’m looking for a way to create a press mold where I want to keep a consistent thickness gap in between the inner press and the mother mold.

Maybe there’s a better, simpler way to achieve this?

Any help would be great, thank you!!
