Motorized Cube Gear with Stepper Motor

Based off of the original cube gear and the motorized cube gear. I made this design to be operated by a common and cheap stepper motor (Stepper Motor 28BYJ-48 With ULN2003 Driver). This does mean you will need a microcontroller to operate the stepper motor. I used an Attiny85 to be able to fit within the small box enclosure. These microcontrollers are tiny and great.
