Great advice, I think I found the problem:
I find it's a good practice to run everything you print through NetFabb first. Download the free version and run it through the steps for repairing the part, apply and export it out. Now Import that file into Cura.
Good news. After a combination of the x-ray tool and netfabb, I have a perfect print!
very nice printed model !
Another little tip is.. I find great success in going into the expert settings in Cura and choosing from the Combine Options A.
David really did a nice job of this function and it saves my bacon all the time.

This is a typical problem with Sketchup... After some time I learned how to prevent these red surfaces (inside planes or double planes at the same place) already while modelling. Selecting the whole model and using the "smooth edges" command (I don't know if that's translated correctly, I'm using the german version. See screenshot below) will reveal all "double planes" which occur mostly when you're doing very small surfaces. The lines will not disappear if there are double surfaces.
By the way, this smoothing tool doesn't change any geometry, it just makes lines between surfaces disappear, if the angle between the surfaces is less than the angle specified (I leave this at 20°).
I prefer making a clean model over using the "patch-up" tools, because these don't always work as intended. For example, I'm doing parts right now which will have some structures that are entirely enclosed within the part, because I added supports which make it print better, but lead to that effect. Cura will just ignore these inside structures with "fix horrible" activated. But the structures are necessary because you're supposed to remove the support after printing and then they won't be inside structures anymore...

I was wondering what those options were. I'll try those with my model to see. The model currently consists of 3 components, so that I can edit the sides and the base apart from the structure. To solve it yesterday, I exploded all components and removed a bunch of the lines in between them.

It's probably skipping part of your model.
Look at the model in cura layer view carefully - especially starting where the problem occurs. Perhaps a wall is too thin to print. Cura will print down to .4, .6 or .8mm wall thickness only. Not sure why there are different limits at different times but the nozzle hole width is .4mm so obviously no thinner than that.
Also look at the part in xray mode - anything the color red is a potential problem.
