I recommend printing four, with two of them mirrored left/right by your printer control software. Then you can glue the reversed ones to the backs of the "forward" ones and create double-sided earrings. Of course, you can always just print two and use them as-is, but note that they will be one-sided in that case.

I used a white filament, and used a black sharpie to fill in all of the raised parts.
