Without the model to evaluate, I would hazzard a guess here, that it is a faulty model and it is trying to make 'bridges' between holes: ergo, a non-watertight model.

i repair model with Zbruhs-> Meshmixer-> netfab online -> cura: plugin Mesh. 

but nothing.

Would not know unless the model can be evaluated.

 

And, if this is not for a UM printer, something may be wrong with the printer def.

When I try to slice this, CuraEngine crashes. Before it crashes it says...

I did not see the attached model and .3mf file. So, thanks to @smartavionics for slicing it and making me look again.

 

Sorry about that. Ever since surgery, I am not fully brain ready.

 

But, I did download the model and it checked out fine. I had an issue with the .3mf file opening. Maybe the download was corrupted in transfer.

 

But, I did slice the model using my standard UM printer profile and it sliced fine as you can see below. So, I am leaning towards a bad printer profile.
