I'll help you review this for production ideas to keep costs low. Please send me your details. What 3D or 2D CAD are you using?

Plain banana jacks don't satisfy safety requirements, but some as are used on DMM's have an insulating shield
that keeps conductors covered until connection is broken, and those could be good.

Seems like basic laser cutting, right?

I am very busy designing a prototype with the production power supply

How is it "production" quality of design , yet we haven't heard much about the details of it

You once mentioned, "1A is probably dangerous at 120v. It is tricky to say", so you should
get some review for safety's sake from me, or any others with more electricity experience.
1A is instant heart stopping electrocution current. A salty right hand to left hand connection
would go above the 10 milliamps it takes to disrupt heart beating when driven by 120 Volts.
