Slic3r doesnt slice my 3DS model

I am in the process of drawing a prototype using sketchup and saving the file as 3DS
When applying the file to slic3r in order to slice it appears like this

And when trying to slice ends up like this

The model can be wieved here
skfb.ly/CP8p

What do i do in order to repair the file?
I have made models in sketchup before and saved them as 3DS with a sucessful print, though these models were much more simple.

You need to use netfabb tool to correct your model before using it
