Step 3Prepare the Heat-Shrink Tubing
Heat-shrink tubing is used to isolate the wires at the connector ends. If you are also using the socket pins, the tubing will fit over the pins to stabilize them and make them easier to handle.
Actually, when I first designed this, I hadn't planned on using epoxy on the connector, so needed something to make sure wires didn't touch each other on that end. If you use epoxy (or epoxy putty) you don't actually need the bits of heat-shrink tubing there, though they do add a nice bit of color if you use clear epoxy. SO, use them or not.
For the six (or five) bits near the right-angle pin header, you can use 1/4" pieces of tubing. For the other end, 3/4" is necessary. If you don't want to think too much, you can probably just cut all tubing pieces to 3/4". Note, that I used two different colors making the "F" pin different from the others just to make it easy to recognize for orientation.
