The file 'Compact Disc (CD) Balloon Hovercraft 3D Printer Model' is (ipt,stl) file type, size is 276.0KB.
My daughter needed to create a air powered "thing" for school and I found this instructable: http://www.instructables.com/id/Balloon-Hovercraft/
Since I didn't have a wooden spool, but I do have Autodesk Inventor and a 3D printer I decided we should design an adapter. We measured some CD's and our balloon and created a CD Balloon Hovercraft Adapter.
The part prints easily and snaps into the center of the disc easily.
Note: You will need a pretty smooth surface for this to work, we used our kitchen counter.
