Enceladus with known topography scaled one in ten million

Originally published here: Enceladus with known topography scaled one in ten million by tato_713 - Thingiverse

This model is made by myself using MATLAB R2016a on the incomplete map from Schenk (2009) filled with the low resolution map from Tajedinne (2017). Some features can be artefacts of the overlying between the maps. It's scaled to 1 in 10^7 or one in ten million. The model of this has about 5cm in diameter. On this scale the Moon is a basketball. It's also included a one in four million scaled model for more details, which model is about 12 cm.
The file's names explained:name_1_x_10_y.stl is 1 : x* 10^y. So _1_6_10_7 is 1:600000000 or one in 60 million.

S2 Enceladus

Enceladus is the sixth largest moon of Saturn. It looks like a smaller version of Europa, one of the moon of Jupiter. Both of them have a thick water ice crust, stripes and water vapor "geysers" at the south pole. It is widely accepted that both have subsurface oceans, responsible for tectonic activity. The "snow ball" appearance is because of the falling material from the "geysers". The escaping material is the source of the E ring of Saturn.
