Copco Bamboo Wood Lazy Susan, 14-Inch

Why would you attached the top to the bottom with a tiny screw that will come out when you try to turn the lazy susan?????

Does anyone no how big the lip at the edge is? I’m getting a piece of stone to go in the middle.

Interior diameter between lips on 14"? And to confirm lip height? Using for a craft project.

Is this food-safe? I want to use it as a charcuterie board.
