Upvote for Overture, my favorite.

I’m a huge fan of Overture 3D matte PLA. It’s inexpensive, and just prints really well with few problems.

At some point you’re going to need to recalibrate your printer. The prints just won’t be as good as they should. And it can be very very frustrating trying to figure out what’s wrong. I highly recommend this website: https://teachingtechyt.github.io/calibration.html
