Mercedes-Benz Vito / Viano / V-Class W638 3D-printable parts
Free STL files for replacement parts, clips, brackets and accessories that fit the Vito / Viano / V-Class W638 (1996–2003). Print at home in PLA, PETG, ABS or Nylon.

Floor Air-Ventilation Grille
Replacement floor air-ventilation grille identified by the creator as A63882701397C65. Source photographs show the physical grille installed in the carpeted floor opening. Use tough cabin-heat- and abrasion-resistant material, match the opening and colour/trim version, clear every slot and edge, seat the grille flush without trapping carpet, and confirm unrestricted airflow and clearance from feet, seats and movable interior fittings.

Gear-Selector Internal Repair Set
Two internal replacement parts for the gear-selector mechanism. The creator identifies exact chassis fitment, supplies a physical source photograph and states that one O-ring is required to retain the assembly. The archived files were 3MF containers carrying misleading STL extensions and are preserved for upload with corrected .3mf filenames. Compare both original profiles and the selector version, use tough cabin-heat- and wear-resistant material, fit an oil-compatible O-ring of the correct size, and verify every gear position, detent, indication and interlock repeatedly with the vehicle stationary before road use.

Front Air-Vent Horizontal Fin Assembly
Replacement horizontal-fin assembly for the internal front dashboard vent nozzle. The creator reverse engineered the part from a van, had it printed in nylon and used it in the left vent; the source only suggests, rather than proves, that other front vents share the same internal geometry. Match the original left-side fin assembly before use, print in tough cabin-heat-resistant material, finish the pivots without removing retention features, and confirm every fin moves freely, stays aligned and does not obstruct airflow.

Rear Door Stop
Replacement stop for the rear/tailgate door locking mechanism, identified by the creator and model filename as 6387400003. Source photographs show the loose original-style child from both sides. Use a tough, weather- and impact-resistant material, compare the mounting and contact faces with the original, preserve latch and seal clearances, and verify the rear door closes, latches, opens and remains aligned without binding before driving.
