DIY 3D printed stepper motor


Christopher Hawkins made this cool DIY 3d printed stepper motor:

This is a programmable stepper motor and driver that I made out of some nails, magnet wire, neodymium magnets, a digispark microcontroller, and a 3D printed piece that I designed around these things. My goal was to make something about the size of a business card that moved. You can’t exactly fit it in your wallet but it does indeed move. It just a first draft- there’s lots of room for improvement. It has a step angle of 15 degrees (although the way I’m driving it, it is 7.5 degrees.)

    1. I have to say this is very nice work, but at the same time mention it is not an actuator.
      There is no output shaft. It is a pure formality however, very cool work!

  1. Do you possibly have the CAD design of this prototype available? I want to try to make this at my school for a project.
