If anyone can help/advice/suggest please share your thoughts= =2E Is it specifically a truncated icosahedron you want, or a soccer ball? Because there's this: https://en.wikipedia.org/wiki/File:Soccerball.svg which is freely available under a creative commons license. You should be able to use an application like Inkscape (https://inkscape.org/en/) to manipulate that image. There's many other examples of soccerballs available, or indeed truncated icosahedrons. Just google for 'soccer ball clipart svg' Cheers, Matthew --O2nV5FJj7MEtiXEOJ2gkdhr10JdJTtmwc-- --TJeQeaVGMWOA7j1Hh6ToEj2QX5phnMbln Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- iQJ8BAEBCgBmBQJZot95XxSAAAAAAC4AKGlzc3Vlci1mcHJAbm90YXRpb25zLm9w ZW5wZ3AuZmlmdGhob3JzZW1hbi5uZXQ2NTNBNjhCOTEzQTRFNkNGM0UxRTEzMjZC QjIzQUY1MThFMUE0MDEzAAoJELsjr1GOGkAT2IQQAKqnZhtLsoSGlIWub7jxbwuo 000KBke6f1bNAHPByALFwHxvHdg78FlSB5LxiTed9/VYGsntEunnkb9OEVeND9l8 wJNuPu0YMedeSE+qfi+6Sa/ee0TJr1iDaVOrMFyWKcSAap6vVvUQ74zJrsel/YUP S2Wi3Pd1RbulIQdiYjVGxrgukHZk3c5YyOb1JbO1tfb7j00K6g6sainf9aNMYcUw Y1kXqRKUtD2eOIcWMAq0HI5rxhIgLAcwsrasLG9c0qHXR1saMeFkEfLW3ZzFOv3c WJw85ftBoFlQ4COkTZtSpQ6YQdDfB+lwqwf338NYcOHQFjC+awKflsJ4afUUjnR+ irEu3BhzdX+dp0G+bgT3u2LnmcwUtNAyk8Qa2uLuOX5beauS2hLw/qSHp/v2Lx6u 9pyEr24QW7unrn8F9L9cN7yfalsEcx5Jty1GHJq9thDLq1nl/e60G9zmD+YwRjYT 7y0rI61IQHiXASB1dTQHcpul/lA/2E07aW94w72iC5319tL15VKk7N39O6+mfk5Y JoQTPwYJ3l8BcVmNWJRELsAb+K8SR/zv9OeU/qGaz+ZW5ckz239CMyZ7/SP9p16k BuiipmuGFwa948jrYs+Y5u8vupWrHQW+7SZSg3q49OPZ0oVzULGyfEEeTFOkt0kW KM2Wiw/CLWDUufP/bR7N =Owm6 -----END PGP SIGNATURE----- --TJeQeaVGMWOA7j1Hh6ToEj2QX5phnMbln--
