150 mm Microwave Turntable Roller Ring
Replacement microwave turntable support ring for ovens whose glass tray rides on a 150 mm roller track. It has three 18 mm rollers on radial pins, a 168 mm OD ring and a loose 36 mm hub that drops over drive couplers up to about 34 mm. The ring, rollers and pins are all PLA with no metal inside. They print together on breakaway sprues: snap them off, drop each roller between its cheeks and push the headed 4 mm pin through, where the inner cheek grips it. The tray sits 18 mm above the floor and the ring clears it by 2.5 mm.
