Summary A miniature planetary gear with the PlayStation buttons and logo that magnetically attaches to the back of a Nema 17 Stepper motor. I received a broken 3d printer with a little windmill attached to the extruder, and I enjoyed watching it spin around while the extruder was in motion. I had some ideas, so I decided to make some cool, decorative extruder attachments of my own!

As the motor spins, the symbols rotate around the PlayStation logo! Here's a clip of it in action

The files included are multi-material files. To make remixing easier, I've also included the Fusion 360 project!
