Very nice!    Looks like I need to make a trip to home depot.  I have been doing similar with multiple size cups and trying to use rope to provide tension.  This looks like it would work so much better. 

Thanks!  Actually working on another version....  This is a mock up of the new prototype.  One half of it at least.  Think of it as two of these, connected together with short copper link in front, a longer copper chain that wraps around your back and two copper chains straps running over your shoulders.  Like a copper bra.  The suction cup will pull each breast through the oval base which will be tight against the chest.  Need to solder this one together, try it out and then pickup some more fitting to complete the other half.
