Endless wall thickness help

Hey there. Trying to get something 3D printed, but any time that it's sliced, it disappears. I cannot get the G code because of this. I modeled the model in 3DS Max, and have shelled the object up to 10mm thick to create wall thickness and it's still failing. Could really use some help, been at this for weeks. I have put the object through shapeways and fixed the walls and it's' still failing. If anyone could help me out, it would be greatly appreciated.

Try putting it through the netfabb repair service. https://modelrepair.azurewebsites.net/
