3D Api nodes saving file name

### Feature Idea

Hi,
I just tried meshy6 api implementation and wanted to make a suggestion:
It would be better to have a text input to specify the directory and name where you want the file to be saved instead of the result ID on output dir.

It would benefit to have the same file saving system as "Save Image" and "Save Video" Nodes with built in date formating system, thus providing a easier pipeline for batch processing.
