the ryobi end need support to print.
the makita end need to be flipped upside down, and also need support.
the inner member, need to be laid flat with the widest face facing down,
but don't need support.
the clip buttons need to be turned 90 degrees on it's side, but don't need support.
I used the metal terminals from broken ryobi lithium battery,
but the terminal can be made from 0.6mm thick sheet of metal 12mm x 30mm.
need to fold one end twice 2mm apart, to hook it over the inner member ears.
