thingiverse
An inverted clock in which the numbers turn and there is only a single arrow as a hand. The clock is meant to be read from the inner circle out, straight up from the 12 o'clock position, if it wasn't already obvious.
I've included a picture of a motor I believe matches the exact dimensions of a similar motor I picked up locally at Michaels used in this machine.
