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.
