What each part record includes
The 166 catalog separates files by exact generation. Each part record brings together its STL files, compatible vehicles, recommended materials, dimensions, category and source attribution.
Reinforced Sill-Trim Support Bracket
Modified sill or rocker-trim support bracket with dimensions and geometry changed to simplify printing and increase strength. The remix and its source explicitly identify Alfa Romeo 166 fitment; compare the original bracket and mounting geometry before installation.
Sill-Trim Support Bracket
Replacement support bracket for the sill or rocker trim. The source explicitly identifies Alfa Romeo 166 fitment; compare the original bracket and mounting geometry before installation.
Powered-Seat Drive Gear
Replacement drive gear for the powered-seat mechanism. The creator designed and printed it after the original plastic gear broke in their Alfa Romeo 166; compare the original gear, tooth form and shaft fit before installation.
50 mm Alloy-Wheel Center Cap
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.
Idle-Control-Valve Sensor Cover
Replacement cover for the Bosch idle-control valve sensor used on the 156 and 166. The creator designed it because the original cover is discontinued separately from the complete sensor.
Right sill-trim clip
Right-side replacement clip for retaining the sill/side-skirt trim. The creator specifies supports and PETG; mirror the model for the left side.
