MercedesMirrors

Mirror-Adjustment Handle

Two-piece handle and lock for the 5 mm manual driver-side mirror adjustment rod. The creator explicitly states W123, W124, W201 and W126 fitment. Use tough cabin material, check the rod diameter and locking engagement, and confirm full mirror travel without forcing the cable or mechanism.

Ignition-Key Handle CaseC3D–01597
MercedesDashboard & controls

Ignition-Key Handle Case

Two-piece replacement case for the handle portion of the original ignition key blade. The creator provides separate upper and lower shells and shows the physical case around a 123-series key. This does not reproduce or alter the metal key blade or lock coding. Verify the blade head dimensions, bond the shells securely with no adhesive on the blade cuts, and confirm the case cannot separate or obstruct full key removal.

Seat-Cushion Upholstery ClipC3D–01581
MercedesSeats & restraints

Seat-Cushion Upholstery Clip

Replacement clip joining seat upholstery to the internal metal rod. The creator explicitly states use on W123, W140 and R129 seats and recommends ABS rather than PLA. Compare the original clip and seat construction, use a tough heat-resistant material, round and clean every contact edge and confirm the upholstery is retained without cutting the fabric or affecting seat adjustment. Source-stated numbers 1239884078 and 1409883778 were not assigned because an independent exact EPC child-component mapping was not recoverable in this run.

Ashtray-Replacement Storage SetC3D–01598
MercedesConsole & storage

Ashtray-Replacement Storage Set

Multi-part replacement for the centre-console ashtray: a storage body plus shallow, flush, blank and outlet-ready plate options. The creator shows the body installed and notes unused space beneath the extended plate for a separately wired 12-volt or USB outlet. Use heat-resistant material, retain safe selector clearance, secure the assembly, and fuse and insulate any electrical addition independently; the files contain no electrical hardware.

Heater-Control ButtonC3D–01596
MercedesDashboard & controls

Heater-Control Button

Replacement heater-control button intended for a two-colour surface indicator. The creator used PLA, 0.08 mm layers, ironing and 100% infill; for automotive cabin use, choose a heat-resistant compatible material and preserve the visible indicator. Compare the shaft interface and confirm the control operates through its full range without binding.

Fuel-Tank Vent BellC3D–01595
MercedesCooling, fuel & exhaust

Fuel-Tank Vent Bell

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.

Centre-Console Switch PanelC3D–01594
MercedesDashboard & controls

Centre-Console Switch Panel

Panel and two separate mounting clips for the upper centre console, demonstrated with 300D switch hardware. The creator recommends screws and nuts rather than pop rivets and notes that the face can receive wood veneer. Compare the switch count and opening layout, use cabin-heat-resistant material, keep fasteners and adhesive clear of wiring, and confirm all switches operate freely.

Washer-Pump Reservoir GrommetC3D–01593
MercedesWipers & washers

Washer-Pump Reservoir Grommet

Flexible grommet sealing the windscreen-washer pump to the reservoir on a 300D. The creator specifies flexible filament and 100% infill. Clean the reservoir opening, compare both pump and tank diameters, use washer-fluid-compatible TPU and confirm a leak-free seal before closing the bonnet.

Rear Speaker Grille for 5.25-Inch SpeakerC3D–01592
MercedesCabin trim, cargo & roof

Rear Speaker Grille for 5.25-Inch Speaker

Modified rear-deck grille for Rockford Fosgate R1525 5.25-inch speakers, derived from the creator's credited earlier grille design. The source specifies ABS or another high-temperature material to avoid cabin-heat deformation. Secure the speaker independently, verify grille retention and keep the installation clear of rear-window visibility and parcel-shelf hardware.

Headlamp Mounting NutC3D–01591
MercedesExterior lighting, cameras & sensors

Headlamp Mounting Nut

Replacement headlamp mounting nut shown beside the original physical component. Compare the thread, diameter and lamp position before use, print in heat- and weather-resistant material, tighten only to the original retention load and verify headlamp aim and stability after installation.

Engine-Bay Fuse-Box LidC3D–01590
MercedesEngine-bay electrical & sensors

Engine-Bay Fuse-Box Lid

Replacement lid modelled for the fuse box on a 230E. Other engines are explicitly untested, so fitment is restricted to the demonstrated configuration. Reuse the original gasket and fuse-card insert as instructed, print in engine-bay heat-resistant material, verify full sealing and latch engagement, and never install a warped lid that could admit water or contact fuses.

Centre-Console Cup HolderC3D–01589
MercedesConsole & storage

Centre-Console Cup Holder

Two-cup holder shaped for the centre console and demonstrated by the creator for saloon and estate interiors. The creator printed at 50% infill and fixed the holder with hook-and-loop tape. Use heat-resistant material, secure it without drilling or trapping wiring, keep containers clear of the selector and controls, and verify that it cannot become a loose object under braking.
