The prompt
Create a 3D CAD model of an air purifier filter frame. - Design two square panels that hold a removable filter between them. - Each panel must have exactly 20 rows × 20 columns of square openings (400 openings per panel). - Connect both panels with an integrated plastic living hinge along one side. - Add integrated snap-fit tabs on the opposite side to close and reopen the frame by hand. - Add two small mounting tabs on the top edge to fit into the air purifier housing. - Use realistic, lightweight, injection-moldable plastic geometry with rounded edges. - Use millimeters and editable dimensions. - Export as an editable STEP (.stp) file.
