GPIO Connections

I am struggling to find a good interconnect method for GPIO to sensors.

I bought all kinds of lures and hats plus capes.
This one is my favorite so far but I dislike the phoenix connectors.
They don't seem rugged enough for me. I want seriously positive connections.

So I messed with terminal strip for GPIO output.
Mounted on lid of APU2.
Not satisfied. Couldn't find size I wanted.

Now I am building my own breakout board in the alpha stage.

3 binding posts with Positive, Negative and Signal for 15 GPIO Pins. Red/Black/Yellow
Mounted on a piece of plastic 12"x 3"
I am not using bannana plugs.
I am planning on soldering the tabs on the underside of the board for power and signal.

I am using the knurled nut on top of the binding post for a fork spade connector.
Using external 3V power source.
Running 18/3 thermostat wire to each sensor.

This was my inspiration for this project with many tweaks:

How do you breakout your projects to the real world?
 
I felt the need to grow beyond the limited footprint of a cape or hat.
I have big fingers and wanted room around the pins to hand tighten the nuts.

Revised my design. APU2 and RockPro64 are well along:
