Printed at 100% scale, 0.4mm nozzle, 0.1618 layer height, 25% infill, 5 top/bottom layers, 3 shells, used raft and supports. Couple of notes: If using simplify3d or any slicer that allows you to seperate connected surfaces you can do so and print the star seperate from the moon. If you don't have a slicer that will do this you can still print it with the star attached to the moon. Also the model is not able to sit upright on its own, it is a bit top heavy and must be glued down to some sort of base. Auto-Supports didn't generate good enough supports and they failed on my first print, causing the moon tip at the edge of ring to seperate from the rest. Just keep in mind you will need to add manual supports as well. Also, if you print this with the moon and star separate, take a small file to the insides of the rings to make assembly easier so you don't break the rings.
