Every printable part.

Replacement 12-tooth drive pinion demonstrated in an Australian-compliance 1989 560 SEC instrument cluster. The creator printed, fitted and updated the gear profile after road use, and reports continued odometer operation. Fitment is restricted to a matching 12-tooth cluster; do not assume every 126-series speedometer uses it. Support the rotor shaft during press-fitting, preserve end float, have any desoldering performed competently, and verify accurate speed and distance readings before road use.

Spacer ring developed to retain a near-match replacement dust boot on a 126-series rear self-leveling-suspension hydraulic strut when the original boot is unavailable. Source photographs show the physical ring and boot installation. This is a protective-boot adapter only, not a suspension load path. Match the replacement boot and strut dimensions, use oil-, weather- and fatigue-resistant material, and inspect hydraulic lines, clearance, leaks and boot retention before returning the car to service.

Replacement plastic trim panel surrounding the bonnet-release lever on a 300SD. Only the creator's revised R2 file is included; it raises the screw bosses and shortens the shoulders after the first version did not sit flat. The creator explicitly says it does not fit a 123-series car. Use heat-resistant material, retain the original fasteners, and confirm the panel sits flat without restricting full release-lever travel or bonnet-latch operation.

Two-place cup holder shaped for the 126-series centre console and shown installed over the roll-top compartment in the creator's source photographs. The creator printed it in PLA at 20% infill, sanded it and painted it; the preserved STL is non-watertight in an independent mesh audit, so inspect and repair the sliced geometry and choose cabin-heat-resistant material for vehicle use. Secure the holder without damaging trim or wiring, keep containers clear of the selector and controls, and confirm it cannot become a loose object under braking.

Replacement trim clip for the towing-eye cover on a 126-series car. The preserved author archive supplies the model, licence and exact fitment, while the only source image is a CAD render and no physical make is shown. Compare the original clip and cover position, use UV- and weather-resistant material, and confirm the cover cannot loosen into traffic.

Fits S-Class · W126 / C126

Replacement closure/side-guide piece for a centre console with a wooden roll-top. The creator copied the original for a 560 SEL, reports that the final file is installed and working, and also labels the application C126; because that body-code wording conflicts with the 560 SEL model name, compare the console and original guide rather than assuming every saloon or coupé uses it. Use heat-resistant material and confirm smooth roll-top travel without stressing the wood or adjacent switches.

Fits S-Class · W126 / C126

Two replacement seat-adjustment levers for the opposite seat sides on 126-series interiors. The creator printed both successfully in ABS and emphasizes that the documented print orientation is important for strength. One preserved STL is non-watertight in an independent mesh audit, so inspect and repair the sliced geometry before printing. Compare the shaft and lever direction before choosing a side, use tough cabin-heat-resistant material, and confirm the seat locks and moves through its full range without binding.

Fits S-Class · W126 / C126

Replacement stop for the sunroof-motor clutch adjustment on a 126-series car. The creator designed it after the missing part allowed the roof to drift out of adjustment and states that the part should work directly from the printer. Use cabin-heat-resistant material, compare the original drive version, set the clutch and travel according to service instructions, and verify complete opening, closing and manual emergency operation without binding.

Fits S-Class · W126 / C126

Replacement rubber buffer insert for a door striker, explicitly designed for the 126-series. The printable is only the sacrificial insert, not the metal striker or latch assembly. The creator specifies printing on its side with build-plate-only support and 100% infill. Use durable flexible material, compare the original insert and striker geometry, and confirm both primary and secondary door-latch engagement before driving.

Fits S-Class · W126 / C126

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.

Fits W123 Series · W123 / S123 / C123

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.

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.

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.

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.

Fits W123 Series · W123 / S123 / C123

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.

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.

Fits W123 Series · W123 / S123 / C123

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.

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.

Fits W123 Series · W123 / S123 / C123

Replacement 4 mm plastic locking pin for electrical sensor connectors and the Stromberg 175 carburettor valve connector. The creator demonstrates the printed pin with the original sensor fittings. Match the connector body and pin diameter exactly, use engine-bay heat- and fuel-resistant material, route wiring without strain and confirm the connector cannot loosen or short before operating the engine.

Replacement external button cap carrying the hazard-warning triangle for the dashboard switch identified by the creator as 1238200205. The printable reproduces only the cap, not the complete electrical switch, so that assembly number is not assigned. Use heat-resistant material, retain the original switch mechanism and confirm reliable hazard-light activation, cancellation and indicator visibility before driving.

Fits W123 Series · W123 / S123 / C123

Replacement plastic locating pin for the wooden switch panel in the centre console, demonstrated on 240D and 300D cars. The creator provides a central hole for an optional cut-down steel nail bonded with adhesive to reinforce the shaft. Keep metal reinforcement fully encapsulated and clear of wiring, use heat-resistant material, and confirm the panel is retained without stressing the veneer or switches.

Fits W123 Series · W123 / S123 / C123

Replacement door-seal clip measured directly from an original coupé component. The creator tested prototypes in PLA and final parts in ASA/PETG, recommends nylon for durability and specifies horizontal print orientation for strength. Fitment is limited to the coupé body. Compare the original clip, deburr all edges and confirm the seal seats continuously without preventing safe door latching. The source references A0009871015, but no exact independent EPC child-component record was recovered, so no OEM number is assigned.
