Microwave Turntable Coupling

Inspired by Natevw's "Microwave turntable shaft coupling" this replaced the worn coupling on my 20+ year old Kenmore microwave. The Kenmore needed a slightly longer shaft and slightly larger hole. The original coupling is made of nylon and over the years the keyed portion of the hole got stripped out so it would not grip the motor shaft any more, so the turntable would not turn.
