The prompt
Generate the complete 3D model now. You MUST output actual, executable OpenSCAD code. Do not provide a description, explanation, summary, or design proposal. Your entire response MUST consist of exactly ONE fenced code block beginning with ```openscad and ending with ```. The script must create a parametric, 3D-printable, two-piece automotive cupholder system based on my uploaded reference photos. Include: 1. A removable double cupholder with two side-by-side cylindrical drink openings, slightly tapered walls, closed bottoms, thick rounded upper rims, and a smooth, solid front bridge connecting the two openings. The front bridge must fill the inward-facing notch between the cups without obstructing either opening. 2. A separate stationary mounting bracket with a secure sliding dovetail-style rail that accepts the removable cupholder. 3. A matching female sliding channel underneath the cupholder that fits the mounting bracket. Use separate OpenSCAD modules for each component, plus an assembly preview showing how they fit together. Make all major dimensions adjustable using clearly named variables at the beginning of the script. Use reasonable placeholder dimensions for the initial conceptual model. Do not claim the mounting bracket is fitted to the Mazda yet. Prioritize clean geometry, structural strength, smooth transitions, and FDM 3D-printing compatibility. The result must be valid OpenSCAD code that can render without errors. OUTPUT ONLY THE SINGLE OPENSCAD CODE BLOCK. NOTHING ELSE.
