Lazy Susan rotating tray or turntable

For those that entertain!
Here is a 115mm diameter Lazy Susan which should easily take a 250mm serving plate.
All you need are x5 16mm ball bearings or marbles.
Print this off, put it in the centre of your table and place a plate of fancies, Hors d'oeuvre or canapes; which guests can whizz around and choose at their leisure!

Adapted from Thing:316500 which I created as a filament spool holder and dispenser
