I have included the Fusion 360 f3d file so you can make further changes, should you wish.

I also printed this in PETG clear. I liked the white PLA better on my white shade.

I took a photograph of the broken handle, traced it in Fusion 360, and then scaled it using the length dimension that I measured off the broken part.
