The prompt
Create a precise, fully editable, 3D-printable mechanical chassis consisting of exactly THREE identical rectangular plates, EIGHT cylindrical connecting rods and TWO motor-support stands. IMPORTANT: Follow the dimensions and geometry exactly. Do not invent additional components or features. 1. THREE IDENTICAL PLATES - Quantity: 3 - Length (X): 90 mm - Width (Y): 60 mm - Thickness (Z): 4 mm - All three plates must have exactly identical dimensions. - Keep all plates horizontally aligned and parallel. 2. EIGHT CONNECTING RODS - Quantity: 8 - Diameter: 5 mm - Length: 52 mm EACH. - All rods must have identical dimensions. - Four rods connect the bottom plate to the middle plate. - Four rods connect the middle plate to the top plate. - Arrange the rods symmetrically, with corresponding positions between the plates. - Keep the structure rigid and properly aligned. 3. TWO MOTOR-SUPPORT STANDS This section is especially important. Pay close attention to the orientation. Quantity: EXACTLY 2. Each stand must be a SOLID RECTANGULAR PRISM with these dimensions: - Height (Z): 26 mm. - Length (Y): 30 mm. - Thickness (X): 2 mm. PLACEMENT: - Attach both stands to the BOTTOM plate. - Place one stand along each of the TWO OPPOSITE SHORT EDGES of the bottom plate. - The short edges are the 60 mm edges, NOT the 90 mm edges. - Each stand's 30 mm length must run parallel to the 60 mm edge. - Each stand's 2 mm thickness must run perpendicular to that edge. - Centre each stand along its respective short edge. - Both stands must be symmetrical and opposite each other. - Their 26 mm height must extend vertically upward from the bottom plate. ABSOLUTELY NO HOLES OR CUTOUTS IN THE MOTOR-SUPPORT STANDS: - No circular holes. - No screw holes. - No slots. - No openings. - No decorative cutouts. They must be completely solid rectangular supports. 4. ASSEMBLY REQUIREMENTS - Exactly 3 plates, 8 rods and 2 motor-support stands. - No extra plates, rods, pillars or supports. - Ensure the motor stands do not collide with the connecting rods. - Use suitable mechanical connections for the rods. - Keep the three plates identical. - Make the model suitable for FDM 3D printing. - Keep the individual components editable. - Provide a complete assembled 3D model. - Allow export to STL and STEP formats. 5. STRICT INSTRUCTIONS Do not change any specified dimensions. Do not put the motor stands on the long edges. Do not put the motor stands underneath the bottom plate. Do not add holes to the motor stands. Do not add electronics or decorative structures. The result must be a clean, symmetrical, three-level mechanical chassis.
