I recently came across this instructable of a 3D Printed DC Motor and I figured I could take it a stepfurther; Literally. I designed this stepper motor with eight electromagnets, six neodymium magnets, with a 3d printed rotor and stator housing. This is specifically a permanent magnet stepper motor capable of 15 degree full steps and 7.5 degree half steps. There are many different types of stepper motors but most of them work very similar to the one I have designed here. This is an educational display to show others how stepper motors work. I designed this to run on a 5-12VDC power supply so it will work with most USB power supplies.
I am also doing a giveaway on my Youtube channel. I will be giving away an arduino, transistors used in this project, and some switches. More details in the last step of this instructable.

1. Six 1/4" neodymium magnets.
2. 608ZZ Bearing
3. Eight 8d 2-3/8" nails - Not critical what nails you use as long as they fit.
4. Magnet Wire - I used 0.315mm magnet wire but this is not critical.
5. Arduino Uno
6. Four Transistors - I used PNP transistors I had lying around, but you can use whatever transistors you want or MOSFETS as long as you make sure they can handle the current your motor will draw. Read the datasheet carefully for specific recommendations. On 5v mine motor draws about 1 amp and on 12v it demands about 3 amps.
7. 3D Printed Rotor and Stator
9. Electrical Tape
10. A compass
