Mechanical — 3D-printable Mercedes-Benz parts

Flexible replacement tether published specifically for this generation. The creator requires TPU and instructs removal of the lid pin and remaining old tether before fitting the new piece snugly around the fuel cap without affecting its seal. Compare the pin, cap eye, tether length and filler-lid clearance, use fuel-vapour-, UV- and weather-resistant TPU and confirm the tether cannot enter the filler neck or prevent the cap from sealing completely.

Flexible replacement tether for the fuel filler cap, created after the original tether failed and shown installed on the filler door. Print in fuel-, UV- and weather-resistant flexible material, preserve the cap sealing surfaces and venting, keep the tether clear of the neck and hinge, and confirm the cap still seals and locks normally.

Replacement flexible tether for the fuel-filler cap, published specifically for this generation. The source contains a printable model and CAD source image but no cap revision, material or durability test. Compare both attachment eyes and tether length, print in fuel-vapour-, UV- and weather-resistant flexible material and verify the tether cannot enter the filler neck or prevent complete cap sealing.

Replacement grommet through which the radiator lower locating prongs pass. The source establishes 124-series fitment but provides only model imagery. This grommet isolates and locates the radiator; it is not a structural vehicle mount. Compare the original opening and radiator pin, use engine-bay heat-, coolant- and vibration-resistant flexible material, and confirm secure seating, fan clearance and leak-free hoses after installation.

Direct replacement for the lower condenser mounting grommet identified by the creator as A2019970381. The source model intentionally simplifies fillets and tightens the fit for printing. Compare the original grommet and condenser pin, use heat-, weather- and vibration-resistant flexible material, and confirm the condenser is retained without metal-to-metal contact or stressed refrigerant lines.

Flexible downward-facing bell for the fuel-tank vent line, recreated after rodent damage on a 300CD/T/D application. The creator printed it in flexible filament at 100% infill and describes a friction fit on the black 90-degree elbow. Use fuel-vapour-compatible material, preserve an open vent path, secure the bell against loss and stop if tank venting, odour or leakage changes.
