Can someone tell me why Cura keeps filling this hole?

Now, obviously the most logical answer is internal geometry, but this model has none.

The larger hole is for a power bank, and the smaller for the cord.

I take great care in my models so when something goes wrong, it's quite upsetting. Especially after having spent so long making it.

 

Hell I even tried netfabb. That didn't work, either. I'll include that file as well. I don't think netfabb actually changed anything.

I just don't understand it. There shouldn't be any reason for that hole to get filled up. In blender, that hole was made by extruding a face downward and then beveling the inside edges. Internal geometry would be impossible with that method.

 

Normals are all correct too as far as I can tell

FACEPALM

Nevermind. I figured out the issue. I had a reference block set to hidden that I absolutely forgot was there, and was exporting the entire scene from blender instead of the selected model.

 

Ignore this post. I resolved it myself.

I refuse to ignore it until I stop chuckling.  Congrats on finding the problem.
