It's a clock!

The face is 280mm in diameter. The hands are designed for a Quartz clock mechanism. You may need to scale these up or down slightly for a snug pressure fit - depending on the accuracy of your printer. You can, of course, just print the clock face and use the hands that came with the motor - if that's your preference. I opted to use the thin metal second hand that came with my mechanism. I've included an optional hanging bracket and a spacer for the clock mechanism but depending on the one you have you may not need these parts.
