I finally did it ! Building a sphere and rings with LEGO bricks made by neurons racing, but here it is : The Giant Planet Saturn !
Featuring cloud bands, ring system with the Cassini division.
Also built is a translucent stand to support this massive planet. It may be possible to hang it as well from the pole opposite to the stand with a slight modification of the internal structure (to increase its strengh to the level needed in the hanging scenario).
This prototype is made of 1917 LEGO pieces and has been imagined and built using Studio 2.0 software.
