Hot glue mold for Macbook cord

Made a hotglue mold to fix my wifes frayed macbook charger cable.
The two cable dimensions are 4,7mm and 3,1mm, so if your charger have the same dimensions, this model will work for yours too.
Otherwise feel free to remix my model or be inspired to make your own from scratch.

I apply a thin layer of cooking oil on the mold surfaces in order to ease the separation of the hot glue from the model.
