Unchartedx on youtube shared a 3d scan of a predynastic Egyptian vase. these vases were made out of Granite, and it is not known how they were made to such exacting tolerances.

the original stl file was scaled improperly and full of holes, the interior of the vase was incomplete so I filled it in and repaired the file.

I printed mine with supports and a brim, they may not be needed.
