For my boomerang like desk, i decided to add a "single storey" shelf.
This is were my speakers stand - to lift them with the tweeters to ear-height.
There are also accommodated some critical electronics like power-stips (which I turn on and off multiple times a day), a mixer or the radio system for wireless audio transmission which i wanted to protect from floods of hot coffe.
Scale the caps in the slicer to your needs ; )
eg. scale one to fit the outer to the inner measure you need and lay another besides to scale the inner on it ~ I express myself awkwardly on this but - you'll get it xD
