There is a problem with the hollow parts on the neck, you have a undercut that does not allow for a constant thickness, at 1.8 the surfaces intersect. I'll see what I can do to you tomorrow if I have a little time, but we should review the angles in the hollow parts.
This extrusion must be carried out in several stages, the raw shape (the pan) must be made, then the straight part must be cut at the end and a solution for the handle must be found (reduce the angles). Of course, you only have to work on one half and then make a symmetry.
And how do you want to make this piece (!undercuts!)? What material will it be made of? Then why 1.8mm thick?
Hello
I'm attaching the beginning of a piece (thickness 1.8), lack of time, I'll continue later if I can.

Pay attention to the junctions between the surfaces, they must be adjusted (fusion between the 2 bodies).
Have you tried by creating an outer surface shell spaced 0mm apart and thickening it to 1.8mm?
all you have to do is remove the volumetric body...
All that remains is to refine the surfaces at the level of the recesses in the shell on the handle, the hardest part is done and you should succeed in doing the rest...

The answer chosen is not the last piece posted, this one is not finished.
It is better to choose this one:
