I wasn't happy with any of the available key rings for the great Half Life 2 logo so I remodelled it to allow a see through appearance.
This key ring is designed in 3 parts so as to allow printing with a hexagon mesh and it is split into two colors in the 3MF file, and is printed with a manual color change.
Please use the 3MF file as it has the mesh and color change setup correctly (I have included the STL if required)
The author marked this model as their own original creation.
