3 Sided Mobius Strip

I've been working with an editable mobius definition and I've successfully been able to edit the twist in the surface. , what I'm really looking to do is to make it a 3-D mobius solid. I haven't been able to find enough information regarding the thickening of a surface in Grasshopper and what I am really interested in doing is making the surface 3 sided, so basically like this image attached. Is there any way to do this? I'm getting a little frustrated with the definition and it was becoming too complex before I decided to jump on here and ask more experienced folks!
