Oil-Drain Access Cover

Replacement access cover for the oil-drain opening in the engine-compartment underbody screening, physically shown loose and installed by the creator. BMW catalogs identify this child cover as 51757261712, item 5 in the underhood-shield diagram; it is used on X3 F25 and X4 F26 applications, so both live generations are linked. The printed design uses lower U-nuts and hex screws rather than the original fastening method. Print in PETG or a higher-temperature engineering polymer, confirm the panel variant and VIN, and verify secure retention and clearance before driving.
