That is not a moon!
A flat deathstar version that can be used as Christmas tree ornament, earring, keyring, you name it.
For the earring version, I scaled it down to 80% and printed at 0.15mm, with surface ironing (this is a new option on Prusaslicer beta to make a smooth top surface).
For the Christmas tree / keyring version, I sliced it with a change of color (also possible on Prusaslicer) so that the top layers had another color. This bigger version was printed at 100% scale with 10% infill and at 0.20mm layer height.
So far, tried with PLA only.
