3D Printable Sculpture Skeleton

Hello. I am tasked with making a physical model with an exterior made of fabric. In rhino, I am designing the skeleton to go underneath the fabric, so each fabric face essentially has a border to be glued on. I need to 3D print this structure, but my structure is currently just surfaces. I need to add thickness without compromising the front sides of the surfaces. I tried OffsetSrf + BooleanIntersection but I hadd no luck with that. I have attached a photo and a Rhino File of the sculpture. Thanks!

Maybe just build the exterior surfaces (I did that with only a part), offset them with the solid option, and then, using the automatic construction plane, trim the inner and outer surfaces with your “inner” curves, and finally build the flanges with loft surfaces. That’s a fairly quick way of doing it, but it can probably be done differently, very likely with Grasshopper (which I don’t know or use).

This helps a lot, thanks! How did you get the surfaces that you offset to not interfere with the other faces? Or did you just trim the offset surfaces by the other faces?

I used OffsetSrf with the Solid option after joining all surfaces into a Polysurface.

Thank you very much, joining was the step I was missing!
