I am looking for ideas on something off the shelf or easy to make that
would allow you to parallel multiple sets of up to eight wires using

Everything works but is a little messy with 12 sets of four wires
twisted and taped together.
Do you want something like stacking banana plugs? You can get them in
ones and twos, I don't recall seeing more. However, you can fabricate
(an evil word, sometimes) a bracket or something to hold multiple sets
in alignment. Thinking of standard dual banana plugs, you could put a
screw through the middle of the web between the plugs into a strip along
side however many you wanted, which would hold them in a constant
orientation. A piece of plastic bar, with some notches machined every
3/4" would be perfect. A 3d printer could make a very nice little
fixture to hold them, and then it's a matter of epoxy.
Then just have a row of banana jacks in a panel that connects to your
barrier strip.
You could also arrange banana plugs in some other pattern (square,
circle, etc.).
https://www.adafruit.com/product/3694 are the ones where you just stick
the wire in, crank the screw down, and you're done. A little dab of
thread locker on the screw might be useful.
The other thing is to use something like 1/4" tab connectors, which are
available in multi tab versions, some which are designed for barrier
strip mounting. I'm not wild about these because each mate/demate is
individual.
There are some nice multi tier screw clamp terminal strips (you've seen
them, they're green, usually), and they make a plug/socket version.
this kind of thing:

There might be a stackable version.
It would be great to have a box that had about six sets of eight
receptacles for the same type of terminal block connector as provided
by Green Heron that could be somehow be configured for what you
needed.
Other than an old style terminal strip with screwed down terminals
does anyone have any ideas on how to improve on having a bunch of
wires twisted or soldered together and taped up?
Thanks...Stan, K5GO/ZF9CW
