Sixth Stellation of the Icosahedron

This is the sixth stellation of the icosahedron (well I guess)
See https://en.wikipedia.org/wiki/The_Fifty-Nine_Icosahedra

I generated it tweaking the openscad code of
https://www.thingiverse.com/thing:197620

with this setting
small_stellated_dodecahedron(-3.4317*2.5+2.4317);

Then spend some time in clean up using mesh mixer
Then cut the elementary spike and made the support using freecad.
