The prompt
Modify the current model to fix four geometric issues: 1. Add a solid vertical cylindrical screw shaft (diameter 12mm, length 95mm) connecting the bottom knurled hand knob straight up through the lower jaw of the C-clamp to the circular pressure pad so no parts are floating. 2. Add a 5mm fillet radius to the outer edges of the C-clamp bracket. 3. At the top end of the upper arm tube, add a cylindrical hinge joint (diameter 24mm, width 28mm) and a horizontal spherical ball joint neck (diameter 16mm, length 25mm) extending forward. 4. Move the rectangular phone holder plate (width 90mm, height 65mm, thickness 8mm) onto the front end of that ball joint neck so the upper arm attaches exclusively to the rear face of the plate without intersecting or poking through the front face, and place four L-shaped corner retention hooks on the front face.
