Easiest way to draw it would be to use 3D software for creating the ball and then trace it.

1. Create SDS ball and clone it.
2. Select original and separate all the faces on the object.
3. Select faces and then scale so, that there is visible gap between all the faces and give some thickness with extrude.
4. Render with toon setting and trace the resulting image.
5. Load it in vector drawing software like Xara, etc. and use fills for shading.
