I loved 3dprinting4silvas flex tie, but i wanted to make one that had different designs on the front and back ([m a magician, so i use it for a color changing tie trick)

I took his original design and just changed the attachment point at the knot to a ball and socket joint.  this way you can spin the tie around as needed.  

It is worth noting that in order to get a clean print of everything, i had to seperate the top piece of the necktie from the ball joint…i then glued these two pieces together…there might be a better way, this just made the most sense to me.
