Hold multiple laptops, tablets, or phones vertically in a "mail organizer" style setup that grips to your desk. Add any number of slots, and customize the widths of each slot to hold your devices securely.

You probably don't have exactly the same devices as me, and DEFINITELY not a desk of the exact same thickness for the grippy part! Hit "Open in Customizer" to change from Thingiverse, or download OpenSCAD and change the variables that way.
