Large phone holder

I`ve created this model because i could not find any large and strong enough phone holder which can be installed on a tripod.I`ve added a spring also in order to keep the jaws open ,a m5x70 screw for tightening the phone , there is a m5x10mm brass insert inside the bottom part also there is a 1/4-20 threaded hole for tripod installation.The model was printed using Sakata PETG with 70%infill for extra strenght.If the printes is setted up correctly all the tolerances will work.
