The prompt
Create a parametric CAD model of a replacement internal housing chassis for an Apple iPhone 8. This is NOT a protective phone case. It is the structural housing that holds the original iPhone 8 components. Overall external dimensions: * length: 138.4 mm * width: 67.3 mm * target total thickness: approximately 7.5 mm Create a hollow rectangular phone chassis with rounded corners matching the general shape of an iPhone 8. Requirements: * front opening for the original iPhone 8 display assembly * internal cavity for the original battery * internal mounting area for the motherboard * mounting bosses for screws * clearance around the motherboard and battery * left-side openings for mute switch and two volume buttons * right-side opening for the power button * centered bottom opening for the Lightning connector * openings for bottom speaker and microphone * rear camera and flash opening * separate removable rear cover * rear cover attached using simple screw mounts rather than complicated clips * wall thickness approximately 1.5 mm * use 0.3–0.5 mm clearance for 3D-printed fitting surfaces * keep the interior hollow * avoid supports where possible * make the model watertight and manifold * all dimensions must be editable parameters Prioritize functional mechanical geometry and 3D-printability over visual details. Exportable formats should include STEP and STL.
