Posting here in case this comes up in a search.

First one is done

Filament is Siraya PET-CF. 50% infill, 6 walls, 6 top and bottom layers and I added features to make it solid between the bottom of the coupling nut and the tool chest. I think these are ridiculously overbuilt.

Grade 5 1/2-13 coupling nuts, swivel leveling mounts, and 5/16-18 serrated flange bolts, all from McMaster. The mounts are rated to 3750 lb each and have a 2" stud.

Min height will be right about 4", I'd say max would be 5". That could easily be increased or decreased with adjusting the printed part or stud length.

The McMaster order was $141 and 2kg of filament was $63.

You've mostly redeemed yourself for not purchasing $10,000 worth of welding equipment...nice.

..., it took three tries to get the sizing for the coupling nuts just right due to how the material was shrinking. But I only had to print ~8mm of the leg, so it was about 30 minutes for each.
In cases like that, I'll model a small sample of the part just to check fit then use the dimensions I learn from that on the actual part. That way you end up with 30 seconds of print time per attempt.

I wanted enough thickness to represent what might happen with the part at full size, plus not mess with all the wall and top/bottom layers.

And that 30 min includes the 8min of warm up (270 nozzle/100bed!) and calibration

I know **** all about 3d printing and all the different plastic types and how they perform and I'm curious...
Will these settle and compress as they age or more and more weight get added?
Will this plastic age/deteriorate over time and fail?
Will heat or cold cause any issues?

There are a ton of different filaments with an amazing array of properties.

This stuff is very strong and dense and has heat resistance well beyond any shop will see.

I bet it will last as long as I do

I know less than zero about this stuff.

How do you embed a coupling nut? Print, stop, position, continue, ?
In this case, it's just an open pocket that it slides into after the print is done. If any aren't tight, I'll use some gel super glue.

If you want it inside the part, then yes, you can have the printer pause at a specific layer so that you can place the nut, magnet or other hardware. If using magnets, you need to use a brass or stainless nozzle to avoid picking it up
