To make your dome model begin by printing pages 2 and 3. Enlarge them on
a photocopier about 150 - 200% and print on thick paper or card stock Cut
out the two main pieces of triangles along the perimeter edge lines. Next
bend the edges by placing on a straight edge on each line. A counter top
with a sharp edge works good. Finish both sections by taping together nearest
edge lines shown, and finish the model by taping together the two sections.
Optionally cut out tabs for gluing together with white glue. This
gives the 2 frequency icosahedral dome, 1/2 sphere.
The gray areas represent the Base Option. Five of the Base Option triangles
are missing to allow viewing inside the dome.
