Tycho Crater - 13 hours


I recently discovered that NASA has a repository of lots of 3D models and files available to download. As I sorted through them I discovered the Tycho crater (the big circle on the lower 1/4 of the moon in the image below.
Tycho Crater

Tycho is around 86km across, and my print is just around 80mm across; giving this a scale of around 1,000,000:1. The print is a topographic model of the the crater, with ridges rising and falling, and the "island" in the center. The peak is 1.6km in real life, and around 1.5mm in print. The whole tile is 98mm squared (3.8")
