Design a 3D-printable Mechanical Advantage Jar Opener with functional gear/lever system. Mathematical Movement Constraints: Axle-Hole Clearance: Apply 0.45mm global clearance on all articulating joints and pivot pins to prevent fusion during printing. Gear Module: Use Mod 2.0 tooth profile for maximum torque transfer. Ensure 0.5mm backlash between meshing teeth. Leverage Ratio: Handle-to-grip distance must achieve 3:1 mechanical advantage (e.g., 150mm handle length for 50mm opening radius). Structural Requirements: Wall Thickness: Minimum 3.5mm to prevent delamination under 20Nm torque. Internal Support: Design internal cavities compatible with 40% Gyroid infill. Printability: Design with 45-degree overhang limits for support-free printing. Output Format: High-poly STL/STEP file with completed non-manifold geometry checks.
