The prompt
Design a 3D-printable holder that prevents an open PVC window from swinging in either direction. Use a screw-operated C-clamp attached to the sill and an upper U-shaped cradle gripping both sides of the bottom sash frame. Include rubber pads, adjustable height, and a lockable vertical-axis swivel. Use reinforced plastic parts and standard metal screws. Make key dimensions parametric. Provide separate printable parts AND a fully assembled CAD model, showing installation on a window sill with the window open. Export the assembly as STEP and individual printable parts as STL.
