This is a small shelf with adjustable legs designed to go on top of a TV. You can use it for, remotes, set to boxes (appletv, roku, etc…) I have prented 2 and use them to hold up my ound bar.
The author remixed this model.
I've lengthened the front lip, shortened the overall depth, created shorter leg options, as well as thickened it slightly and added a grid support on the bottom. This should help keep it from sagging over time.
