I’m modeling a handle part like the image above, but I don’t know how to create a surface that connects the body and the handle. Please help me😢

I keep missing the continuity of the surfaces in the blue circles in that image

The image below shows the current situation where I’m trying again from the beginning.

If possible post your 3dm file so it would be easier to analize the surfaces and give you better answer.
