blue square lid 3d model

Lid specifications: The outer shape should match the square base. The underside of the lid should include matching holes (female features) aligned exactly with the base pins. Hole diameter should be slightly larger than the pins (+0.1–0.2 mm tolerance) for smooth fit. Hole depth should be slightly more than the pin height. Fit and finish: The lid should sit flush on top of the base. Optionally, add a small internal lip or edge to improve alignment and stability. Edges can be slightly filleted or chamfered for better usability.
