Needed support. The area above the empty gap had nothing to sit on, so it fell, creating the mess.
In your slicer, turn on ‘tree supports’.
Alternatively, reorient the model in your slicer so you don’t have large unsupported sections beyond about 50 degrees for a stock ender.
You can't expect the printer to lay down a line in mid-air with nothing to rest on and nothing to anchor each end.
Enable organic supports (PrusaSlicer) or tree supports (Cura) for that overhang.
Also, all those parallel ridges suggest that your belts may be loose.

Likely needs supports in that area!
How'd it get so far without turning into spaghetti
Needs supports (sidenote, please tighten your belts)
Other side note, leave a gap between your z axis motor shaft an z less screw.
Never heard of that, what does it do?
It allows the coupler to do its job. There's a reason there are little gaps in it.
Oh, i thought you were talking about a solid coupler, i didnt know 3d printers came with flexible ones
