Flashring (Godox Ar400 or Flashpoint Ring Li-On)

Description

This is a Powerfull Flash ring for Macro fotography, portrait fotography and Photogrammetry. The model was made with a structured light 3D scanner and shuld have an accuracy of around 0.1mm in most places. I will be using it to model a polarizing add-on to do crosspolarization for photogrammetry and other experiments.
