This is another snowflake earring. This one is based on the Koch fractal or Koch Snowflake fractal, just the initial equation, no iterations/recursions.

Printed in PLA with a 0.3mm nozzle. The line thickness in the model is 0.9mm, so you'll need to do a manual extrusion width of 0.3mm slicer setting. Or you could use a 0.4mm nozzle which would almost come out right.
