How to make the two ends (marked them green) merge?

Hey, a beginner question. I modeled this hexagon thing and want to model this shape onto its faces.
I sketched the shape, shape binded it two times into the Hexagon's body. Moved and rotated these Binders so they're congruent to the faces. Then padded them.

Now how do I make the marked ends connect so that the form "wraps around" the hexagon? Like this:

Thanks for your help.
