The prompt
Redesign the air purifier filter frame with these corrections: - Create two thin, flat square panels that fold together like a book, with a removable filter between them. - Each panel must have exactly 20 rows × 20 columns of SQUARE openings, arranged in a straight orthogonal grid. No triangular holes or diagonal mesh. - Connect the panels with a small, flexible living hinge along ONE outer edge. Do not create a thick side wall. - Add a simple integrated snap-fit latch on the opposite edge to lock and release the panels. - Place two small mounting tabs only on the top outer border, outside the grid area. - Keep both panels aligned and parallel when closed, with enough internal clearance for the filter. - Use clean, realistic injection-molded plastic geometry and export an editable STEP file.
