There are two models: a tray and a C-bracket to clamp the mount to a PrimeCables standing desk in order to keep it off the surface of the desk. The original switch dock fits snugly to prevent it being lifted when the Switch is removed from the dock. For that reason, a switch OLED dock likely won't fit without some modification.
The clamp mechanism uses four ¼ inch heat-set inserts and button head cap screws to mount to the leg of the desk.
The author marked this model as their own original creation.
