This is the first version of an adaptive car phone holder, we recommend printing with tree supports with a cantilever angle of 30, 10% infil, 2 walls, we recommend using supports only for plate number 2 and 3 for number 1 are not necessary. When all the pieces are printed the assembly is quite simple, as regards the elastic stop piece they must be glued to the side of the rectangular holes of the frame, before gluing them you must pass an elastic band of about 80 mm through both rectangular holes. Finally, 2 rectangles 2x4x5.5 mm must be glued to the main shafts in the appropriate hole.
