Microwave turntable couplers, custom printed

The tri-arm hub that spins the glass tray. Motor shafts are D-profile — 7 × 5mm on most models, 8 × 6mm on some larger ones. Pull the old coupler off (it lifts straight up) and check the bore; the tray stops turning the moment the D strips.

Match the bore to your shaft, pick a style and color, and get a print quote before entering personal details. Shipping is calculated next. Or download the STL free and print it yourself.

Pull the broken knob off and check the shaft first — then set the exact bore. Replacing the full set? 4+ knobs get 10% off automatically.
