Replacement door-seal clip measured directly from an original coupé component. The creator tested prototypes in PLA and final parts in ASA/PETG, recommends nylon for durability and specifies horizontal print orientation for strength. Fitment is limited to the coupé body. Compare the original clip, deburr all edges and confirm the seal seats continuously without preventing safe door latching. The source references A0009871015, but no exact independent EPC child-component record was recovered, so no OEM number is assigned.
