Pieces of part missing after slicing

Hi, I'm trying to print a part with a fairly complex geometry (cogs, etc) and after slicing, the center of the spring is missing (red arrow on the screenshot). Any idea what could be causing that?
Also if somebody has a "best practice" list of things to check for model integrity, I'm interested (so I don't have to waste people's time on the forum
)
Factory file:
STL:

Thanks!

Its got something to do with the wall thickness. Slicing at .02 extrusion width gives a little more...and you can get single wall thin extrusion to show......but the issue is definitely with the model.
3D Builder on Win10 doesn't help.
btw a factory file has a suffix of .factory, and is created from the File dropdown menu....Save Factory file. a .fff file is only the settings....and is difficult to use for diagnosis of an issue. The factory file holds everything needed to investigate a slicing issue. You don't need to supply the stl file separately.

Thanks for the answer @dkightley!
Here is the factory file.
By ".02 extrusion width" you mean 1.02 extrusion multiplier? (my extrusion width is currently set to auto eg 0.48mm = 1.2*my nozzle diameter)

I've just stumbled on a magic fix for you......
Mesh dropdown menu.....click on Separate Connected Surfaces.
And I think that's it!! You should now get a good slice.....

It worked! Thanks Doug!
(I would have posted some pics of the printed part but my attachments don't seem to want to save)
