The prompt
Create a functional automotive trunk button housing frame for FDM 3D printing. Fixed outer frame dimensions: 52.3×14×12.8 mm. OEM automotive replacement part style. Rectangular bezel with rounded edges, strong rigid walls, 1.5–2 mm wall thickness, 1.5 mm front border. The housing contains an internal cavity for a sliding button, two precise side guide rails, rear mounting area for a micro switch, and locking clips for installation into a trunk lid. Design for PETG or ABS printing on Elegoo Neptune 4. Add smooth surfaces, reinforced corners, and realistic injection-molded automotive geometry. Functional mechanical part, not decorative.
