Single print folded flat.  Another builder had something very much like this but it was way too tight to open after I printed it (6.5 hours)  and it snapped like a potato chip.  This one is 99% perfect to open after a slow print and no supports.  The 2 wing page holders are a little finicky though and are just a tiny bit too tight.

Try it out.  It's pretty nice even to just use for a tablet stand.  ENJOY.
