The medallion worn by the witchers of the griffin school.
Based on a game model for The Witcher 3 - The Wild Hunt.
I extracted and heavily edited the mesh to make it printable:
Adjusted proportions
Cleaned up the mesh
Flattened the backside to get an ideal print surface
Added a new ring (Both in favor of the flat backside and my personal liking)
A whole lot of manual adjustments and fixes on the mesh
Overall this took far more time than I expected, but I really like the result.
