Ikea Koppang knob replacement

When one of my kids, strip down the original knob from screw, I just made this replacement. And when I made it, my wife like it, so she want this knob on other furniture. Especially she liked that she can choose from different colors so it fit in the color combination of room/furniture (pink one for pink girl cabinet and blue for teal boy cabinet…). First two photos is printed knob, last two photos is from original Koppang.
