The source recommends printing solid PETG because its PLA retaining clips broke, and the photographed part accepts a separate 50 mm emblem. Confirm the wheel opening and original cap diameter before installation. The single-cap STL is supplied; the optional four-cap print plate and editable SketchUp source remain preserved in the audit archive.

Compare both pieces with the originals before installation.
