Iphone / Samsung / Tablet / Ipad anything smartphone STAND - pivotable

Hi guys, I designed this stand based on another one I saw here, will reference it later (can't find it), but that one needed adjustments before it could work and I actually broke the item while pivoting/adjusting the stand. So I designed my own stand with a screw to hold it together. The mating surface holds it up together well. I made the mating hole .2 mm larger for this to happen. I will keep fine tuning the design. Any comments are welcome.
