A pentakis dodecahedron is the 60-sided solid created by taking a dodecahedron, and converting each pentagonal face into a 5-sided pyramid (or invert the pyramid to form a 5-sided depression).
These are designed to be cut from one (or more) sheets of standard US Letter or A4 paper or other more rigid
materials. Once cut and folded, they can be assembled into 3-dimensional polyhedra. Depending on how large you print,
this could be delicate work!
The design can also be just printed onto paper and then carefully cut out with scissors or an X-Acto knife.
There are fold lines and cut lines provided in separate layers, as well as tabbed versions (for glueing paper
assemblies) and non-tabbed versions (for cutting out of other materials -- you'll have to figure out
how to connect them).
