Hole Not Printing


I am struggling with this model printing. The hole in the middle of the print seems to fill in when I send it to print.

Any help would be much appreciated.

Reverse all the blue faces, they are the back faces and should be facing in. Also remove the internal face that isn’t needed. You can see the extra edge showing on the face.

Thanks for this.

It looks like that has sorted it!
