Hello, when I give a thickness to the 3D model I drew in Rhino, the product explodes. When I make a shell, it explodes again. How can I save the model? It all appears as a surface now?
If you haven’t saved it yet, you could always undo the shell. You could make a copy of it before you try to shell it, then you have the original.

If your offset distance is larger than the smallest radius, the offset will typically fail.
Yes, unfortunately there are places where the radius is small, but is there a different command? I think Rhino is limited in this regard.
Its not a Rhino limitation, this happens across all CAD programs.
If your use is only for 3D printing, you can use Shrinkwrap, but that produces a mesh.
If you need the surfaces as NURBs you will unfortunately have to manually create surfaces in the problem areas.
You could use use subd to NURBs process to create the surface for the interior from the Shrinkwrap mesh if you really need the NURBs. there are some limitations in the complexity of the surface for this process, but it might work for this object.
I understand, thanks
I just added to my reply above, you could try Shrinkwrap and then generate NURBs from that.
So how can I do it?
A different approach. Create temporary surface without the ornamentation. Make sure it either coincides with the original surface or is inside the original surface everywhere. Then offset the temporary surface and use that offset as the inner surface. The wall thickness with be variable but for most purposes that should not cause any problems.
