NASA Moon Trek: Hesiodus Crater, Mons Pico, Plato & Tutorial
Description
**NASA Trek Moon, Mars, Mercury, Vesta, Ceres web “Generate 3D print file” tool** In order to help students easily (as easy as TinkerCAD) make their own terrain models of favorite regions of the Moon & other solar system bodies supported by JPL's "point, click, drag" online NASA Trek tool, I have provided key screenshots as well as described the basic steps of the process in the lesson included below the specific printing suggestions & details. By using "Vase mode", excellent prints may be made in a matter of several hours on common modest printers. For fun, I have included several interesting examples of Moon .STL terrain models I generated using this method as well as an image I took of the Moon highlighting a few shadows.

In the MS Windows platform, with the included "3D Builder" app you may easily adjust your exported .STL/.OBJ to repair the mesh, view the wireframe, simplify triangles, extrude to add depth, increase the vertical exaggeration by scaling only the height/z axis, etc. Two examples adjusted to x6 height exaggeration provided as .3MF files (which may be printed via Cura slicer just like .STL) Related projects that may be of interest: * [Lunar Crater Chain Mendeleev: NASA Moon Trek Chang'e 2 DEM 20m https://www.thingiverse.com/thing:487976](https://www.thingiverse.com/thing:4879761) * to celebrate the 2021 February 18 arrival at Mars of Perseverance Rover & Helicopter, please see this related [Mars project & model: https://www.thingiverse.com/thing:4747950](https://www.thingiverse.com/thing:4747950)
