Which Stepper Motor?

Hi folks,

I'm in the process of putting together a Timelapse Rail for my GoPro Hero 4. Have the plans drawn up, going to make it for my end of year project in my engineering course. Just looking for a stepper motor that will move around 2mm every 10 seconds or so, I don't know much about stepper motors and either does my electronics instructor (weirdly). Any advise?

Thanks in advance,
Chris :slight_smile:
