About this 3D model

This model is a combination of the 3 Valles Marineris meshes provided by NASA here: http://nasa3d.arc.nasa.gov/detail/valles-marineris-6x The models were originally created by Northeast Planetary Data Center, NASA RPIF System, Seth S Horowitz & Peter H. Schultz. I have combined the 3 meshes into one continuous model, and optimized it to reduce the polygon count while retaining the important details. This print was scaled to 18cm, and printed in PLA. It was then painted with acrylics and inks. It looks good mounted on this wide display stand: http://www.thingiverse.com/thing:1363286
