145 / 146 145 / 146 (Tipo 930)

Replacement 50 mm center cap for alloy wheels using OEM 60652886. 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.

Two-piece replacement for a bonnet stay-rod holder, comprising the main support block and its retaining clip. The source identifies OEM references 7622907 and 60810130 and explicit Alfa Romeo 145/146 fitment. The creator printed both pieces in PLA at 0.2 mm layers with supports; PETG is additionally recommended here for engine-bay heat and snap-tab durability. Compare both pieces with the originals before installation.

Adapter for mounting a standard tweeter on the original 145 tweeter mount. The creator glued the tweeter to the adapter and removed the front grille and bent the tweeter wire pins to fit the available space.

Redesigned support for the bonnet prop rod. The creator reports that the earlier PLA version lasted more than two years, recommends PETG or another heat-resistant material, 40% infill and supports, and added a screw to retain the rod when the support yields.
