I printed this mini benchy with my Creality K1 and a 0.2mm nozzle using the Sunlu matte PLA, the walls was 0.21mm and the layer height 0.1mm using the creality slicer (I just changed the line width and the layer height). This was my first print with this nozzle so it need to be tuned a bit, but the result is still impressive, even the smallest detail are visibile.
