iPhone 4 4S holder attachment

iPhone 4/4S holder attachment for GRIPGO mobile phone car holder. There are 2 versions to it. Labelled "L" is for iPhone 4/4S with moshi cased. "S" for iPhone 4/4S without any casing i.e. iPhone only. The internal holding width of "L" is 60.5mm, "S" is 59.2mm.
This design is a result of my many trials and iterations. To date, it is the design I like most. Minimalistic, sleek and classy, the attachment itself is sexy enough to be stare upon.
