Slicing failure (too many holes?)

I tried slicing the attached model and this happened:

I guess it could be too many holes in the object so the slicer gets confused what's inside and outside? Are there any settings to fix this?

The slicer file is attached: FailedSlicing

Hi Pavel, 
As soon as I open the file, I see  

the Red triangle with the exclamation mark inside, shows that there are errors in the STL 
Use the 'Fix Through the NetFabb' tool

Many, thanks. That fixed it indeed. I didn't know about this useful feature. It's interesting that it failed only for the last copy of the same object. I created it in OpenScad and it's the same thing copied over several times.

Anyway, thanks again.

RE: Slicing failure (too many holes?)

Openscad quite often produces 'broken' models.  Spend any time over on the Prusa Slicer github and half the 'incorrectly sliced' issues raised  are down to openscad models.

I do think that Prusa Slicers error checking could be better as Cura seems to handle things better but the Fix through Netfabb option (at least on windows 10) can be a lifesaver.
