I designed these Happy Birthday earrings in several programs. I advice you to print them slows (30mm/s). If you have printed 'em for that special birthday party, don't hesitate to show of your skills and upload a picture of your print. It would make my day!
It's party time people╰(°▽°)╯ !!
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.
