It’s a mains blade interface, basically 0.2mm thick piece of sheet metal that is stamped and then bent. Here is a short blog for more context: Mains Blade Interface | Details | Hackaday.io
I’m, of course, willing to pay for the work; I would pay for prototype qtd. then move to Asia when getting into higher volume (if you can do high volumes (20k+) for a reasonable price, that’s better).
I would provide more complete drawings.
