I found a nice photogrammetry scan of a Socrates bust and fixed it for 3D printing. It is located at Winthrop Hall, UWA - Australia.

I did a remesh, sculpted some areas and cut a flat base. This should be printable without support material.

The original file can be found here and viewed in 3D: https://sketchfab.com/models/8e6613f59628417bbcb0e5b888b41162

I also added a zip file containing a full color model.
