Cable Loop Holder (iPhone)

PLEASE post your makes this is my first model and I would love to at least hear your opinion and how I can refine it.Really simple to use insert one end of cable either lightning or USB-C into one of the holes in the centre. Wrap until you reach the middle with little cable left and insert the last end into the opposite hole.I used supports but not too sure if really needed if someone finds out or wants to test otherwise please tell me how it went.
