Summary of 3D Printed Stepper Motor
Christopher Hawkins created a compact, programmable 3D printed stepper motor designed to demonstrate motor mechanics. Using nails, magnet wire, neodymium magnets, a Digispark microcontroller, and custom 3D printed parts, he achieved a business card-sized device capable of rapid movement without losing steps. Although labeled a first draft with room for improvement, it successfully demonstrates a 15-degree step angle (functioning as 7.5 degrees in this configuration).
Parts used in the 3D Printed Stepper Motor:
- Nails
- Magnet wire
- Neodymium magnets
- Digispark microcontroller
- Custom 3D printed piece
Check out this cool 3D Printed Stepper Motor that Christopher Hawkins made. You can see in the video that it can move quite quickly and not loose any steps. This design would be idea to teach how stepper motors work.

“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.)”
