This structure has 12 pentagonal holes. It is built from a Rhombicosidodecahedron, whose pentagons are replaced by 12 pentagon and triangle cupolas.
The cupolas are then joined by means of squares and hexagons.
We used 30 blue squares (with blue panels) and 20 blue equilateral triangles (with blue panels) for the Rhombicosidodecahedron in the centre, 120 orange triangles (with green panel inserts) and 60 green pentagons (with orange triangular panel inserts) for the 12 cupolas, 20 purple plain hexagons and 30 purple squares (with purple panels) to join the cupolas.
