The outer skin of my iPhone charging cable used for Carplay was damaged, It's not safe to use without a protector.
I browsed the makerworld and found this lightning cable protector that fit my taste. However, the protector didn't fit well. Later I realized my cable was a USB A - Lightning cable that come along with iPhone 11. I adopted the design and made a smaller protector for it. Also made some small improvements
If your cable is Apple - 3.3' USB Type C-to-Lightning Charging Cable, you can use the "big" version.
If the cable is Apple - 3.3' USB Type A-to-Lightning Charging Cable - White, you can use the “small” version
