Speaker front cover frame

I made the front frame of my speaker (S-40K). Modifications, I removed the curved circular ring because it would be difficult to print with the ring. It took about 1.56 hours for the crelaity Slicer to print. After printing, I smooth the surface with sandpaper and paint with a thin coat of black nail polish. It looks great in real life! Much better than without the frame.
