Apple 30 pin connector strain relief

I dont really like the charger cables for apple stuff, they bend and break too easy. (no strain relief) its almost as if they are designed to break.
I made this for an ipad cable, I think iphone etc are the same.
Just print (must be ABS for flexibility, PLA will break) insert the cable in the obvious way. it will take up most of flex, but it could probably be improved with a bit more tweaking.
I used 1 wall and 15% fill, you might be able to do 2 wall and 0 percent fill for more consistant bending, need to test a bit more
