“Faith” word art, with the T in the shape of a cross.
The “F” is connected to the “A” by a discrete connector towards the back of the model. In the 3MF, this is designed to be colored differently to further enhance the discreteness.
Note: Keep the back of the model (first layer) a single color, to enhance the strength of the connector piece.
Additional note: The 3MF is at 250% the size of the STL. Scale as desired.
