Macropad (Saturn shaped board)

I'm currently a beginner working on a space-themed Macropad after exam season. I will be using the Hackpad guide to help build the circuit board. Key features I plan to add (correct me if I'm wrong): Use KiCad to create a circular Saturn outline with rings; Center the four keys and knob so they fit on the board ; Space out the four keys (happy to hear any feedback)
