    Schematic

    Since my goal was to design a PCB that looked like an ornament. I figured that a CR2032 would be the best battery to fit there. I found SMD(0603) and through hole LEDs and Resistors on Digikey, after using an LED calculator. While choosing a switch, I wanted to use a Pushbutton. I found one with an On-On Function(When you press it, it stays in the on position until pressed again). So you don't need a latch.

    The Edge Cut was designed by using a circle shape, which was easy to draw in KiCAD. After that, I filled the board with a ground and power pour, and the only other layout needed was to route the battery to the pushbutton.

    I made the Through Hole version by replacing the SMD LEDs with 3mm LEDs and the resistors with Through hole versions.

    Fun stuff
