This includes the button and a face for a floppy drive. The button snaps into the ejection mechanism and is kept straight by the face panel. The face snaps into the bottom portion of the floppy. Top portion tabs of the floppy face are a bit finicky (kept breaking off). I used tape to assist the top tabs.
Second image shows the tape and final assembly. First image shows the tabs working without any tape. Lastly the third image shows what type of floppy drive was used. The face panel in that image was a placeholder.
