Seeking ideas on how to rotate a plate (think lazy susan)

I am trying to add a way to angle a tool and it would be fantastic if there was some sort of plate which I could rotate on top of another plate using the help of a stepper and worm gear. Not sure if there's a name for this but I'm leaning towards "lazy susan bearing" except with a bit of preload on the bearings and less wiggle.

Has anyone seen such a thing made using OpenBuilds stuff?
