I have printed them using PLA with the (bq prusa i3 hephestos) , these are the printer settings:

Layer Height = 0.2 mm

Wall Thickness = 1 mm

Top Thickness = 1 mm (5 layers)

Bottom Thickness = 0.2 mm (1 layer)

No need for Rafts or supports.

For the Moon Infill Density = 0% , for the rest of the parts infill Density = 100%

In total you will use just 79 grams of PLA.

Check the screen-shoots of Cura, for further details. Moon is a bit tricky as you have to move on the Z axis down 5cm.

Or just download a cutted version that JetGuy "Unknown" have create using Netfabb.
