I found the gap in the original design unnecessary as it just makes the great design less stable. I also made it 1mm longer so it fits better in place without vibrating. Finally I fixed the mesh and changed orientation.
Since I don´t have the original file, the mesh looks still not perfect but you can print it in place and get a perfect fitting stable camera shade that also protects the camera from slight crashes.
Special thanks to @MagicFred, the original designer.

I printed this in ABS which is light but stable. I used only walls and no infill. Print it as it is and make sure to only print supports as in the picture.
