Lid for Amplivibe's hardcase wallet

This is a printable lid for Amplivibe's hardcase wallet http://www.thingiverse.com/thing:116831
I was having difficulty getting a standard card to slide over the stop, so I made on with a little protrusion at the end so you can lift is slightly to slide over the stop. On mine I also printed my name and phone number. Ive included the sketchup file here in case anyone wants to do the same.
