I need your help

Hi everyone,
I’m new to 3D printing and still learning how to work with STL files. I found an STL that is supposed to let you add any logo you want, but I’m not sure how to modify it.

I’ve watched a few tutorials and tried using Tinkercad and Bambu Studio, but I haven’t been able to get it to work.

If anyone could point me in the right direction or explain how to add a custom logo to the file, I would really appreciate the help.

Thanks in advance!
