This is a Celtic turtle earring (2.0). I recommend to print it slow, in about 30mm/s. I have designed this model in several programs. I hope you like it. If you have printed this ( or another) model, don't hesitate to show of your skills and upload a picture of your print.
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.
