2. Structural Integrity⁷
   B side features must be designed to withstand mechanical stresses without causing defects. For instance:
   • Ribs should have a height-to-thickness ratio that prevents sink marks on the A side.
   • Screw Bosses need sufficient wall thickness to avoid cracking under load.
     Proper design ensures the part remains durable throughout its lifecycle.
3. Manufacturability
   The complexity of B side features directly affects the mold design and production process. Considerations include:
   • Draft Angles: Features should have draft angles of 1°–3° to facilitate ejection from the mold.
   • Undercuts: Require side actions or sliding shutoffs, increasing mold costs.
     Simplifying features where possible can reduce production expenses and lead times.
