A couple days ago i just wanted to 3d model something so I decided to model a little machine but I felt the need of a good model of something that a lot of times is used by 3D printers, robot and automation enthusiasts…
A stepper motor.
So I downloaded some blueprints from the web and decided to spend a couple hours on it.
Here’s the result after a nice render:

And here it is the back of the motor:

If you like the model you can download it for free from my Grabcad account here:
