I'm still spelunking in the drives in the 466 DA for the Illustrator files I did of the traces on the surfaces of a depopulated Card Cage (bake & shake) and then within the Card Cage's PCB back when I decided to start scanning the it periodically . . .

. . . after taking a grinder to the freakin' thing . . . repetitively! }

It was paper thin when I'd finished, I'm hoping to find it in one of the boxen along with this Duo case I modded for a test fitting! :approve:
