Decided to pull this out of the 3D printed objects thread so I can briefly log the refining process and not further clutter the former.
One thing I have noticed, however, is that it still does tend to extricate one half of the CPU's pins first. While I was a bit cavalier in saying there wasn't any harm in it, it's probably not the best in the long term.
My next point of improvement will be fine tuning the threads. I'm printing out some test bits now to see how much finer I can make them so there's a more even lift. I suspect the current size causes a bit of a shimmy as the thread pitch is pretty tall. With the original metal version, they could simply select a fine pitch right off the shelf and there wouldn't be any issues of uneven upward lift.
If adjusting the thread pitch isn't enough, I may have to resort to widening the puller's depth(?) to cover a larger portion of the ceramic's surface area. I wonder, too if I can make the top section of it slightly thinner. I think this could have two advantages:
I was not paying attention to grammar... "one point for improvement" might've been better...anyway, it was supposed to be an admission of incompleteness. And while I did sort out where the issue is coming from (mis-scaling on the puller threads) I did manage to create a proper one. One should be able to slip the puller on and then thread the bolt on without any issues.One larger point of improvement: for sure is the threaded portion in the 'puller' piece: I had to insert the 'threads' piece by wrapping it with some padding and using pliers to get it seated. This might be the nature of the print support quality. Also I should note: I got the bolt piece in while off of the CPU. The pictures imply one could just thread it in by hand... I would definitely do this OFF the CPU.

- it would permit a slight flex, allowing it to actually slip over the edge of the ceramic
- and when it's pulled up, and from the center, it might keep the puller from slipping out: instead pinching it
- The bolt piece could be very gently tightened to further lend to this pinching action
