This is the far side of the moon. The side we never will see in real life. I used marble gray as light gray.

Print at 100% infill with a layer height of 0.08mm with a base layer of 0.16mm

Filaments Used:
Black

Dark Gray

Esun Marble (you can use a lighter gray)

white

!!!! It appears you have mixed filament types. Be certain this is what you want. !!!!!

Swap Instructions:
Start with Black
At layer #7 (0.64mm) swap to Gray
At layer #10 (0.88mm) swap to darker Gray
At layer #16 (1.36mm) swap to White for the rest.

Happy printing and don't forget to share your make.
