Cura slice problem

[DEAWid 0]

Hello, I have problems with simple stl object in cura.

Object looks fine, but when I slice it, it's not correct.

 

BUT, when I rotate it 90°, slice is correct..

 

Can someone help me what is wrong and how to solve it ?

 

Tested on cura 4.11, cura 8.x etc ...

 

 

Sending screens and stl object in attachment .. only screen "a5.jpg" turned 90° is correct ... a4.jpg, a3.jpg is wrong.

 

Thanks for help

Hi @DEAWid this is because your model is not watertight. This message pops up when I opened your stl. 

 

You could fix the model in a CAD program and that will probably solve your issue.
