So my first tray stand required a rotating hinge. This not only added another component to the construction, but also made the stand somewhat flexible. In addition, the rotating hinge wasn't particularly robust - having some play in the joint. Checking out laser cut ply inspired a different design below.

Add to that, the single leg joint was stressed and under pressure broke. Back to the drawing board for version III.
