Choose card stock or heavy paper that is compatible with your printer. Copy paper can also be used, but more rigid paper will produce a more sturdy structure.
Print a two-dimensional truncated icosahedron pattern on the card stock.
Cut around the edge of the pattern.
Fold and unfold the pattern along each solid line. Folding will make the structure easier to assemble.
Find two hexagons that are separated by a tab. Apply glue to the top surface of the tab on the one hexagon and tuck the sticky side of the tab under the adjacent hexagon. Press down on the tab to secure it. Repeat for all the neighboring hexagons separated by a tab.
Find a tabbed pentagon that is adjacent to a hexagon. Apply glue to the top surface of the tab on the pentagon and tuck the sticky side of the tab under the adjacent hexagon. Press down on the tab to secure it. Repeat for all the neighboring pentagons and hexagons.
Find any remaining unattached tabs. Apply glue to a tab, and tuck the sticky tab under the nearest neighboring side of a polygon. Continue until all tabs are glued in place and the final structure forms a closed sphere.
