OK here are two copies. The real deal, 12V-battery with breadboard life size, and 12V-battery-mini with breadboard around 1/4 size. Breadboard is less than perfect as I am not a graphic artist. Perspective is wrong at least and it isn’t all that detailed, if there is a graphic artist out there, a fix up would be appreciated, a fixup in Inkscape with a log of what you did and how, to educate the ignorant would be awesome! Schematic and pcb are identical in both parts, only the fzp file and breadboard change. PCB has pads that should accommodate 14GA wire (the holes are 0.07in) as these things will provide a lot of current potentially and the board needs to be able to deal with it.

and the pair of them side by side in breadboard:
