Real size Soccer ball (assembly type)

This is a soccer ball made by combining 20 hexagonal parts. The size of the assembled soccer ball is 22 cm and 15cm in diameter.

A real soccer ball is made of a combination of hexagons and pentagons, but this model is made of only hexagons, and the pentagons are holes.

The ingenuity in the design is that the back side is designed so that the bridge distance is shorter.

[assembly]
Join each part with the binding bands. 60 bands are required.
The dimensions of the hole for band are wide 3.3mm x height 2.5mm.
