I made a part with multiple pieces put together, made them one body but seams wont go away and when i print it they print as seperate parts put together. I want them to be one seamless part but cannot figure out how to. file attached

I don't know why your Combine > Joins are not working, but might have something to do with, 

blue sketch articles

Moves

Capture Position,

empty sketches

empty Components, 

a timeline that goes off the page, 

Simpler to build in place, to draw one quarter and mirror twice.

Might help....

@davebYYPCU provided you with an expert level example for modeling the geometry, but my guess is that you do not yet have enough experience to follow the Timeline to really understand the solution.

Would you like step-by-step instructions on how to use Fusion to model your geometry?

This video shows where you didn't get accuracy.  If you elect to continue the discussion, I can provide step-by-step instructions.
