This is a computer graphics test model that was 3D scanned from a terracotta model in 1994 by Greg Turk and Marc Levoy at Stanford University.

Converted from the original bun_zipper.ply file.

I modified the mesh to give it a flat bottom so that it prints more easily and doesn't require removing supports from the underside.

Pictured here printed in PETG Translucent (Olive Green).
