I originally tried the other model and found my keyboard was slightly different being a k95 so adapted the rear to allow its use on this keyboard also. Like the original, it sits right over the buttons 
It gives you quick access to the deck as it sits close to the F keys.

You will need to print 2 of these.
Slide the each one onto the deck, then slide the complete assembly onto the keyboard. You'll have to close the keyboard foot and then open it again once it clears.
