Good news, everyone! I assembled the 67F/16.2V capacitor, complete with cables and charge balance board.  Let me show you the various lengths of wire I used:

I 3D-printed some spacers to keep the caps in line, bolted the terminals together with hex standoffs, wired the charge balance board to each node, clamped on the leads, then taped it all together.  Afterwards, I insulated the whole assembly in a few layers of tape to avoid nasty shorts.

Now, I have to charge it.
