[Why is cura not working for my print.]

Thank you, Putting it into Netfabb worked. You can also use an obj. (maya does not export in STL)

[Why is cura not working for my print.]

I have been trying to figure this out for hours. Every time I combine these meshes in Maya, the cura print software tells me there is an error in xray mode I have no idea what the error is. Please

Help.

 

 

  The two meshes separated.

 After I combined them, merged them, and Cleaned them up. 

What it looks like in cura. 

 X Ray mode in cura telling me there is an error.
