Well that was the problem, thanks for everyone's input.

So I sliced and printed a different model, and then rotated 1 by 180°, it is somewhat weird as the lowest part on the right model seems ok but as the wall built up on the inside it was getting the artifacts. The model on the left was getting the artifacts on the outer piece but not the inner.
In rotating the models after, the artifacts are on the opposite side.
I noticed it was starting at the seam, I have the scarf joint on contour, and noticed that "scarf around entire wall" was checked so trying reprinting to see if that is the issue.
Good point, I have mainly been printing these items for the hydroponic tower. I do have other versions that I can check. I think after this set prints I will add some basic shapes in different orientations to see if there is issues still.
That being said I did print some other items that were stacked and each one is much thinner but there are no artifacts on the outer walls.
I re-lubed the rods before starting another set and still having the issue. I was thinking it had something to do with the Bowden tube but even at the back where the tube doesn't move much the issue still happens.
Is there a specific lube that is better than others?
Thanks for your reply, to your point yes they still fit, been having this issues for a bit now as I'm up to about 40 of these netcups and the associated other pieces for the grow towers.
I think the belts are good, but will double check.
Easy there pussies can be useful, unlike that shitheel.
Almost forgot, Teaching Tech has a great calibration web site and YouTube channel.
My first suggestion if you have a Raspberry Pi Zero 2w or better is to install Klipper. If that isn't a route to go down for you then Myers firmware was really good (not sure if it's still around since I went to Klipper).
I've printed so many miss for mine, spool holder moves to the side, filament guides, different spool holders with bearings, new hot end fan assemblies ,small tool holder that slides into the v slots. Covers for the V slots.
It's a great machine to learn and tinker on, some people don't like that but I really enjoyed it.
I've since switched to direct drive instead of the Bowden tube and added another Z rod and stepper. I have a microswiss all metal hotend which has been fantastic and I have put Noctua fans for the heat break. Also upgrade the Bowden tube to the Capricorn type, it is much better.
A magnetic build plate from Biqu was another good addition.
Almost forgot, I printed risers for the feet out if TPU and that seems to help, I probably would have tried the ones that the squash balls go into but these work fine. In order to print TPU with the Bowden tube you need to print slow.
Also keep an eye on the plastic handle on the filament extruder, they are known to be weak and crack, a good aluminum dual gear is a good low cost investment.
Search on Thingiverse and Printables for mods for the Ender 3 and you will be overwhelmed with your options.
Patience is a virtue, and remember there are no stupid questions and a huge community of people willing to help.
If there is anything else I can do to help, don't hesitate to ask.
That sounds like an interesting plan, my E stepper driver was what acted up on my 4.2.2, it seems to be working now, but I'd like to see your config in case I need to go in that direction.
Update:
I took everyone's advice and tried all the suggestions. In the end I completely disassembled the printer and made sure everything was square or perpendicular where it needed to be. I think maybe the dual z screws were binding, although when I took everything apart I noticed that I did not use the Y cable for both z steppers, I ran the original short cable to one motor and
the Y to another, not sure if that had any effect or not, but now the Y cable is running both z steppers.
It does seem to be better, but I still have the dip in the bed, which is still a bit of an issue for the BL Touch, but not nearly as bad as before. I may have slightly bowed it when trying to crank down the levelling wheels.
I think that the z screws were binding just enough that it couldn't keep up with the micro adjustments, I guess time will tell.
Thanks for everyone's input and advice, hopefully it'll run for a couple more years. If not then a replacement Bamboo might be in order.
Now I just need my resin printers to stop failing prints, but I think that's more me than the printers. lol
Thanks everyone.
It could be that I am cranking down on the wheels too much. Thought that maybe they were loosening off so tried to tighten them. I'll keep that in mind when I reassemble the unit.
Thanks.
I agree on the podcast front, and what makes it worse it's for their own podcasts which aren't generating them any revenue so why have 5 minutes of ads 3 x per show for your own stuff. Not unless the other podcasts generate revenue through ads, but I doubt it, just getting you used to it for when it becomes a Black Mirror episode and you must watch your ads as prescribed by the government (aka business).
