As far as i know, the only new thing about my design is the use of two "combs".
To put the wires in a straight line next to each other.
Which makes it a lot less messy.
And easier to see both sides of the wires.
And easier to see what connectors there are on both sides.
Two combs is easier to use, for me at least.
I do not think i ever saw something like this with two the combs.
And all the other parts on my design have been done before by other people. As far as i know :-)
