Une Bobine is approximately 600mm (24 inches) long. When the end of the cable is coiled to provide support for the base, you can easily place your iPhone between 175mm (7 inches) and 250mm (10 inches) above the table or desk.
Petite Bobine is half the length at 300mm (12 inches) long. It can be coiled in the same manner and provide a slightly lower and more compact stand.
Please look through the project and update photos to see all of the many orientations. We have also posted a short video of some positioning testing that shows some very unique positions
