Roof-Rack Cover Cap

Replacement cap for the roof-rack system pictured by the creator, explicitly identified for first- and second-generation X5 applications. The source includes a physical printed cap and vehicle/rack context, but does not establish that every factory or aftermarket rail and crossbar profile uses the same interface. Compare the mating profile and dimensions with the missing cap, print in a UV-, heat- and weather-resistant material, and confirm secure retention before driving. No OEM number is assigned because the exact rack variant is not independently established.
