Mars Globes (Highly & slightly exagerrated)

thingiverse

The provided text features a Mars globe model with two file options. The primary file, named "marsglobeexag2.stl," is printed in natural ABS and has a 50x vertical exaggeration. The secondary file, titled "marsglobeexag.stl," is printed in silver ABS and exhibits a 10x vertical exaggeration. The more exaggerated model is ideal for the user's purpose of creating a tactile model to teach space science to visually impaired individuals. The globe showcases Olympia Mons as a prominent nipple-like feature, and Vallis Marineris almost cuts through the shell. The Mars Surface Map by tbuser (http://www.thingiverse.com/thing:25319) was used as inspiration for this model, with the same altimetry source data employed for the heightfield. The globe was formed by attaching a sphere to the heightfield mesh using Rhino3D's ApplyMeshUVN command, adjusting the vertical height setting (V option) during the process to yield different levels of exaggeration. A value of 1 results in the exaggerated version, while a value of 0.2 produces a smoother model.
