A complete round tray table sets from Notre Monde.

Some trays are included and it's as easy as placing them on top of the tables.

Turbosmooth modifier open but I kept it on 2 so it fits perfectly with the welding.

Trays materials are easy to replace if you need any of other options from the supplier. I couldn't add all of them.
