Sliding-Door Latch Push Knob

Two-material push knob for operating the interior sliding-door latch, developed on a 2006 2500 van after the replacement handle tab failed. The source provides STL and 3MF variants plus photographs of the physical knob, and specifies flexible material sandwiched between rigid sections. Clean and repair a resistant latch mechanism rather than forcing it, use tough cabin-heat-resistant materials, confirm secure engagement and verify normal opening, closing and latching from inside and outside before use.
