BMW X4 3D-printable parts

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.

Replacement retaining clip for third-party winter floor mats. The creator designed and physically printed it after the supplied clip broke, and explicitly states it was used for the mats in a BMW X4 G02. Although G20 and G03 are suggested by the source, those fitments are not independently tested and are intentionally not linked. This is not represented as a genuine BMW component and no OEM number is assigned. Use a durable material such as PETG, ABS or nylon, compare the mating profile with the broken mat clip, and confirm that the mat is securely retained without interfering with pedal travel before driving.
