Celtic tree of life earrings. This latest version(2.0) is a bit improved. The ring is slightly thicker. And this Celtic tree of life has a different shape.
Although the Celtic knots move in a continuous line, my printer did use retraction.

I have printed this model with white Ultimaker PLA. I have used a 0.2mm layer height and 18% infill. I have used a skirt and my printspeed was 30mm/s. I used a 0.4mm nozzle and my extruder was 210 degrees Celcius.
