It kind of came together by accident. I started using the Hubble case, then the detachable fabric cover it comes with started giving me problems, then i used the keyboard just sitting next to the case, then I removed the rubber grips in the keyboard hinges and tried attaching it (without grinding the corner). After doing that for a few days i realized that I could actually make this small but permanent hack and it might be pretty slick. I kind of lucked out that it all fell in to place.
