Stovall's Flicker nest box is very similar in shape to the 2H. It is made out of 3/4" western red cedar. The predator guard measures as a 5" x 5" plate.  It has a piano hinged top (for adding nesting materials without disturbing the babies) and comes with 2 bags of cedar shavings. The right side also opens for easy cleaning. Sorry - no picture currently available.
