Hee hee!  You made a board layout joke!

Best I've been able to do in that regard is to rotate a 9V battery by 
something like 18 degrees in order to fit it in amongst some standoffs. 
  Fit so tightly, I didn't need to do anything extra to hold it 
stationary, even when you shake the case.  But that was mainly serendipity.
