I am trying to make cheap keyboard riser.
Commercial version is

But this is too expensive for what it does, so I am thinking of purchasing

which will be enough to keep keyboard and mouse, my dilemma is that how to I raise this around 8 inches from the desk? I can keep books but atm I just dont have enough of them.

Please advise
