This model was rendered using MATLAB R2016a on the ICQ model of the PSI made by Philip Stooke from the data of the Voyager missions. The original model has a low resolution, so the model was very "poly" look. To avoid this I interpolate into much more points than the original.
The file's names explained:name_1_x_10_y.stl is 1 : x* 10y. So _1_6_10_7 is 1:600000000 or one in 60 million.
Like many other small inner moons of Neptune, It is though to be a pile of junk from previous moons destroyed after the capture of Triton.
The author marked this model as their own original creation. Imported from Thingiverse.
