Slicing Error in Cura...?

I want to print this Model, but Cura slices it wrong. It Looks completely different in "Normal View" than in "Layer View" and could not be printed like in Normal View is shown.

Please test it for yourself....

The two troublesome blocks on the right side seem to be separate geometries that are just touching the main block of four. The single face where the blocks touch are causing problems - causing Cura to think that the inside is the outside, and vice-versa. Here's how Netfabb sees it:

Internal facets

Three options:

1) Try unioning the blocks together in your CAD package to make a single object (if using e.g., OpenSCAD, I think it helps to have some amount of positive overlap in the objects before adding them together, rather than having them exactly touching);

2) Alternatively, repair using Netfabb to get rid of the internal surfaces;

3) Use the 'Keep Open Faces' and 'Use Extensive Stitching' options in Cura's Expert Settings as a work around to get it to do the right thing.

Or in Cura in exper settings you can simply check "fix horrible" "extensive stitching". This works for your model.

Thank You all for Your Advices. I already checked this with Netfabb and found, that OpenSCAD generates this Error when building the Modell. It's a rounding Error (Scaling). I added a Little Compensation to generate the Modell with no Separation. The funny Thing is how Cura (any Version) Shows the Model and then slices it different.

Thank You All....

by the Way... the Model is for my own Heated Bed Controlle Housing: http://www.thingiverse.com/thing:95994

I love my Ultimaker and with the heated Bed it's more Fun.
