What exactly is an "educated nut" ?

OP here.

I'm sorry, I shouldn't have assumed it was common knowledge amongst the machinist types.

McMaster-Carr sells various types and thread sizes (though none marked like the Bridgeport nut). See https://www.mcmaster.com/#catalog/124/3299/=1cazvlr
Grizzly sells a ⅜-16 pushbutton nut as part number G3717.

I didn't know they were called an educated nut. From now on I'm calling my home made one the PhD...
It's a two piece unit so no mill disassembly required.

AKA Quick Quill Stop or Quick Thread Stop.
Grizzly G7316 - Quick Quill Stop. I had considered one of these for use on a lathe micrometer stop I made, but turned my own nut/scale.

I like the idea. I have a cheap benchtop drill press with a stop nut on a long piece of threaded bar. It's a pain to set up or get up out of the way, so I could see the utility of something like this for more mundane things like drill presses.

I have one of the Grizzly pushbutton nuts (⅜-16) on a threaded rod on my drill press. Even without the graduations, I can "sneak up" on depths by counting hex flats as I rotate the nut. 16 TPI = .0625" per turn = .0625" for 6 hex flats. So one hex flat is approximately .010"

Seems to me, it would be called a Graduated Nut. That's an educated nut that finally finished high-school.

How difficult is this to make.Also why is there a thinner diametr on top of the nut. Is it needed.

There is a version of this that looks like a split nut, spring loaded, that can be clamped on the threads of the quill stop screw. It's fast to use and you don't have to take anything apart.
