Thanks for your replies guys, I could watch those videos all day!

For clarity, yes i was planning on outsourcing them, as there's no way i'd be able to manufacture them myself...

I was really wondering whether the general shape might be unachievable using CNC manufacture, for which the answer seems to be yes. It would seem those machines can do almost anything, but having said that i haven't seen anything that doubles back on itself fully like my "wire 1" part.

Do you guys have any guesses at what i'd be looking at cost wise if i outsourced this to a wire bending specialist?
