Still got poor printing quality after calibrating my Anycubic Predator
A few tenths of a millimeter are pretty common for 3D printed parts; these are related to the printer hardware. These inaccuracies can be exaggerated by over- or under-extrusion; e.g. if too much filament is extruded, it increases the outer dimensions (and decreases the inner dimensions of holes).

The images show some signs of over-extrusion, maybe a little too hot also.
