That looks a lot like what my I3 started doing before I scrapped it.
Mine had the additional complication just before then of forgetting how to print a circle, but that was a more simple matter that the belt holder on the Y axis was doing something weird, and I was able to fix that.
I would suspect some issues with the extruder for the blobbing and layer issues that your print shows. In my case, the extruder was unsalvageable, and changing it out was more of a hassle than I was willing to deal with. I was also never entirely happy with the print quality in the first place.

I also suspect it's the extruder slipping or a half blocked nozzle, motor skipping steps, filament being blocked, constricted, entangled and/or moisture in the filament, bubbles in the filament or inconsistent diameter. Maybe the hobbed bolt is crammed full of plastic and losing grip. Try swapping out the stepstick.
And seeing the bottom of the print there's quite a bit of backlash/compliance judging by the 'pairing' of infill lines and infill not or barely touching the perimeters. All very familiar problems I used to have with a i3 clone before I scrapped it to build a corexy 3d printer.

I once had a very similar looking problem.
It was the heatbreak not beeing secured in the cold end.
Nozzle, heatblock, and heatbreak were tight as they should, but heatbrake was loose in the cooling fins.

My printer was doing that. Switched bearings and reset it up. Worked fine for 1 print.
My issue is that its seems to want to print the same layer a few times. It will do the first few layers fine, then the print goes to shit. If you leave it, it will continue and finish fine. Except it looks like after a few layers it will reprint the same layer a couple of times, then correct itself.
Ever heard of that?
