Lazy-Susan Drink Turntable — 4-cup, drop-in ball bearing

A spinning drinks caddy that keeps turning smoothly even loaded with full cups. The cup weight rides on a ring of drop-in steel balls (NOT printed) so friction stays low under load. Print two parts, drop in cheap 8 mm balls, set the top on — done. Four 90 mm cup wells fit mugs and pint glasses. Parametric OpenSCAD source included.
