This public water fountain was scanned as part of the 2022 Pompeii Water and Sanitation Project field school run by the University of Missouri. The fountain is situated at VI.1.19 and is made of grey peperino slabs. The relief on the spout stone is no longer visible, but was reportedly of Silenus. See this model to see the fountain in a larger context, with the the nearby well that predated it: https://skfb.ly/ovYDy More photos can be seen here: https://pompeiiinpictures.com/pompeiiinpictures/Fountains/Fountain%2060119.htm
The model was generated in Agisoft Metashape from 541 photos taken using a Nikon Z5. Photo alignment was run on high, as was model generation - model has been decimated for export, and made manifold for 3D printing.
