Seeking stl or gcode file for broken part?

Looking out on but struggling to find what gcode or stl file I need to print this broken part on my Mini. Any guidance on the name of the file or any sort of parts diagram I could use to identify it?

Thanks for any help or ideas!!!
Should be what you need.
I didn’t look at the different gcode files to tell what the differences are.

Thank you very much for taking the time to help me you…very much appreciated!!!
