Sorry about the patch you’ve found yourself in - it’s not uncommon in our industry.
You mentioned the previous gig, production mgr /sales engineer - If I were you I might start there, as we are entering a sweet-spot for some manufacturing to pick back up Stateside. Companies like Weathertech, auto industry parts suppliers, appliance manufacturers and HVAC equipment suppliers have kept their US manufacturing efforts since their products aren’t ocean-shippable without undue cost.
And while a true CAD hybrid is super-valuable, your shop-floor experience might be very marketable.
Best of luck!
