This is the Lich King Helm from the World of Warcraft game. The STL is included that is scaled to the size shown in the images. This is a work in progress, I will upload the slices used to create this model once I've fixed a support issue.

Cut the model up using a program like Netfabb and print. I will include the STLs that were used to print this model in the pictures soon. Until then, the entire helmet is in a single STL.
