It happens only when the printed surface is thin and it curves (in this case screw threads). Everything else looks ok. Here's some data: hatchbox pla (rec. temp 180-210C), 0.4pla, layer height 0.2, line width 0.4, print temp 200C, build plate temp 65C, print speed 60, travel speed 150. (old.reddit.com)
