Double wall tube form sealed off in CURA

[Pabloscafe 0]

Trying to print a double wall tube form but CURA doesn't seem to recognise the interior space and is sealing off both ends so it becomes a solid form.  Any Advice?

Hi,

 

I imported your model and cura indeed doesn't recognize the interior space.

 

I set the infill to 0% and the top and bottom layers to 0mm. I sliced on fine- 0.1mm with generic PLA in a 0.4 AA core.

 

Hope this works out for you as I didn't try to print it.

Hi thanks, I managed to get it working.  It appears it wasn't manifold and I also had a few other glitches I didnt spot.  Thanks for the input. Its currently printing so I hope it works out ok.  Cheers, P

Thank you for clearing out that there were problems with your model. 
 

I printed it with above mentioned changes and it worked, too. There was only a little amount of stringing and a little debris inside. I can attach pictures if you like.
