While I’m much happier with the durability (and ease of pluggable use) of Apple’s Lightning cable, I’ve noticed that all my cords have started to disintegrate. Electrical tape seems to extend the life, but doesn’t feel very solid and looks gross especially after gunk starts accumulating on the cord end.
Apparently I’m not the only one since I found this model on Thingiverse to print your own protector.
It’s a relatively quick print at 28 minutes. My main advice is to be sure to add a brim around the edge on this model since it is so skinny at the base. My first print attempt broke free from the glass plate as the leverage applied to it grew the taller the object became.
