Design of spring tip

Hi,

 

Does anyone know what the "correct", or most efficient, way to design something like this would be? I kind of jerry rigged it just to get the job done - my main problem is that the helix part of the component isn't tangent to the right plane and when I did the three sweeps (the base straight section, the helix, and the tip section), there were tiny gaps between the straights and the helix, since it isn't tangent. I then just did a revolved "ball" in each location to fill in the gaps, but surely there must be a way to create this path correctly so that the sweep leaves no gaps.

 

 

Any advice is appreciated, thanks.
