Since I originally did this in Orca I also included the project file for that, which prints faster.

I used Hilbert Curve for the top surfaces because I like the look of it, but just change that back to your preferred pattern if you want. For some reason there was a section in the lower left that did not show the Hilbert pattern but I am not sure why, you can see it in pic 3.

The original image I used is here: Earth’s Moon Poster – Version F (nasa.gov)
