Remixed model to fit as an earring. Actually resized it to x=40.00mm (39.97%)  y= 14.70mm (39.97%) z=3.60mm (56.87%). 

Printed with severals types of PLA on a P1P with 0.08mm layer higth (first layer 0.2mm). Had some problems with bed adhesion so i used brim. Also mirrored modell in slicer to have nice matching parts. Hilbert Curve for surface settings.

Other settings depend on your type of filament or are just standard.
