I need a flat pattern of just the ends of the tubes design, just need it so i can make a template to print and cut out. Any help is appreciated, thanks.

You can move back in the timeline and pickup the straightened length of the previous model.  The main thing you have to have occur to make the pipe unfold with the sheet metal is that the sheet metal body must "intersect" the pipe body by some amount.  In my Screencast I used an offset plane of 0.001" but since you do not have to remove the sheet metal piece, due to the fact you are only interested in the unfolded length, you can make it anything you desire.  If your have to unroll the pipe to get the end profile, you want the smallest engagement as possible but it must intersect. 

Screencast emphasizes this.

Yes, that is the main topic in my last post.  There has to be engagement between the sheet metal and the pipe.
