Questions

What parts does the Stepper use?

10 parts, built around the ATMEGA32-16PU and L293D. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Stepper KiCad files?

From the RavinduLK/CocoExpert-Level1-HardwareProject repository on GitHub, at the commit this page was made from: the board is Simulations/PCB Files/204018x-PCB Files/204018x-PCB Files/stepper/stepper.kicad_pcb and its schematic My Parts/PCB Files/PCB & Schematic Files-Buzzer/Buzzer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Stepper design in my own project?

Its repository states no licence, so its author keeps all rights: ask RavinduLK before reusing the design.
