This is cool, but long-term I’d feel much better printing it in PETG or maybe even nylon. PLA has a habit of “creeping” (flowing like glass) when under sustained load. I think when used like this to hold up something heavy it will gradually pull out of the hole, or lose its grip on the screw, or both, and then fail catastrophically. Could take days or weeks depending on the load, but it will happen.

The main reason we aren’t there yet, I think, is that printer hardware has just been too computationally underpowered to do analysis like that. It’s better now, but you’d still be stuck previewing the output on a tiny screen with minimal controls. Unless you’re willing to put a GPU in the printer, or forego gcode preview entirely — and I wouldn’t trust anything but very simple prints that much — it’s hard to see how to solve that part.

Wrong-filament (and nozzle size, and printer model) warnings are already implemented on Prusa printers, and likely others. It prompts you to specify the filament type when you load it, and there’s metadata in the gcode file header. If they don’t match, the printer complains.
Filament-independent slicing is much trickier, since everything including temperature, speed, cooling, pressure advance, wall order, even support and infill generation can vary.

This is the default value for that field in FreeCAD. It’s the first item in the License menu, and it’s selected when I open a .step file I created myself without adding any license info. I understand why they thought this was a good default, but it should really be “no license specified” because anything else implies intent, but it’s not even possible to select that.
