The prompt
Keep the C-clamp base, vertical post, elbow cylinder, and horizontal arm exactly as they are, and add two mechanical features at the front end of the horizontal arm (at X=-60mm, Y=20mm, Z=210mm): 1. Ball Joint Mechanism: At the tip of the horizontal arm (X=-60mm), add a cylindrical socket collar (diameter 24mm, length 12mm from X=-55mm to X=-67mm) with a side tightening knob cylinder (diameter 16mm), holding a 3D sphere ball joint (diameter 20mm centered at X=-72mm, Y=20mm, Z=210mm) and a short neck cylinder reaching X=-82mm. 2. Split Spring-Clip Phone Holder: Replace the solid phone backplate at X=-82mm with a 3-piece expanding spring clip mechanism consisting of a central mount block (50mm Y width, 30mm Z height from Z=195 to 225, 8mm X thickness), two vertical cylindrical spring guide rods (diameter 6mm at Y=8mm and Y=32mm running from Z=165mm to Z=255mm), and separate upper and lower sliding clip jaws (width 85mm along Y, height 18mm along Z) at the top (Z=240 to 258) and bottom (Z=162 to 180), each with twin L-shaped retention hooks extending forward to X=-110mm.
