I machine 3D shapes all the time for my main job. complex mold shapes etc. So I see some things that I'd like to point out. IF you want to end up with the actual shape you have modeled then the actual geometry dictates what tools you need to use.
Just like Daniel Lyall was saying need at least 2 tools.
So I would break up the job based on key areas as follows:
1) The area I highlighted below in a green ellipse has a very small fillet and it would need a small ball mill to machine like maybe 1/4" diameter.
2) The other end where the neck meets the body shown with a blue line has a sharp corner, it would be best cut with a flat end mill maybe 3/4" diameter something with long flute length.
3) The the area you are most concerned with is the main neck shape. What will be a challenge is the area I highlighted with Yellow arrows. The downward arrow would be best machined with waterline type of milling with a ball mill maybe 3/4 diameter. The yellow arrow that is more horizontal would be surfaces that would be best finish with a parallel cut.
4) Finally as for the red line I show at the bottom, you are concerned a ball mill would drop below... Mount the part onto a 2x4 and elevate it and don't worry about dropping lower.
Hope this helps...
