Reinforced the bottom part (where the cable comes out), because the original one breaks to easily. Also made some space for the cover of the headphone plug ( I have a 'LifeProof Nüüd' cover for my iPhone 5s)
Update: added one for the iPhone without the space for the headphone plug cover and one for a standard usb plug. The one for the usb plug is only half. Print two and glue together.
