Mercedes-Benz SL 3D-printable parts

Replacement folding-roof flap and repair-hinge geometry for a broken small roof flap. The creator designed new hinges that attach to the retained original corner piece because the flap was not separately available, and provides three author STLs plus physical source photographs. Exact model-year, side, facelift and roof-option splits are not stated. Compare the original flap, corner piece and hinge clearances before printing; use UV-, weather- and cabin-heat-resistant tough material, deburr every edge, and cycle the folding roof stationary through its full travel while checking that the flap closes, latches and clears seals and adjacent panels. Stop use if any part binds, cracks or loosens; this repair does not replace the roof lock, hydraulic drive or structural linkage.

Custom dashboard mount for a period mobile telephone, developed on a 1999 roadster and shown installed beside the centre console. The creator modified the telephone lighting separately with a resistor, parallel LED groups, a coiled cable and a 12-to-4 V converter; those electrical modifications and the phone are not part of the model. Match the phone body and dashboard position, use cabin-heat-resistant material, protect trim and wiring, fuse and insulate any electrical work independently and confirm the mount and phone cannot obstruct controls or become loose under braking.

Storage bin replacing the obsolete cassette or CD box in the centre console. The source shows the physical bin loose and installed, recommends 0.20 mm layers and 15% infill and suggests a felt lining. The preserved 3MF loads successfully but is non-watertight in an independent mesh audit, so inspect and repair the sliced geometry before printing. The author distributes it under GNU GPL v3; the API represents that licence as Other. Use cabin-heat-resistant material, check console and selector clearances, secure any retained wiring below the opening and ensure stored objects cannot obstruct vehicle controls.

Replacement sliding clip for the upper row of the lower door/body cladding, developed and tested on a 1999 roadster. The creator reports more than three months of exterior Texas use from 27–44 °C and testing to 233 km/h, specifies vertical print orientation, grid infill and 15% infill, and warns that higher infill reduced performance. The creator was told that similar cladding on 124- and 140-series cars may use it but could not confirm that fitment, so no cross-generation link is added. Compare the original upper clip and cladding rail, use UV-, heat- and impact-resistant material and confirm the panel remains secure at road speed.

Three-piece replacement bushing for the 16 mm ball joint between the windscreen-wiper arm and motor linkage. The creator printed it in PETG at 100% infill, fitted it around the ball joint, bonded the pieces and recommends lubrication. Match the ball diameter and linkage version, use wear-, heat- and moisture-resistant material, preserve free articulation and bench-test full sweep, parking and stall behavior before wet-road use; inspect the bonded joint regularly.

Replacement outer tab for adjusting dashboard air-vent direction. The source explicitly identifies SL roadster fitment and states that only the visible outer portion is modeled; its sole source image is a CAD render. Compare the vent version and remaining inner mechanism, use cabin-heat-resistant material, deburr the contact surfaces and verify unrestricted vane travel without stressing the original vent.

Replacement knob for the access cover on the high-mounted stop-lamp assembly. The creator instructs removing the broken knob base, bonding this print in its place and printing sideways for strength. The cited 1297500039 number identifies the surrounding lamp-cover assembly rather than this repair fragment and is not assigned. Use cabin-heat- and UV-resistant material, choose adhesive compatible with the original plastic and verify that the cover remains secure and the stop lamp operates correctly.

Replacement sliding clip that retains the rear-lamp bulb-carrier assembly. The creator removed the reflector, installed the printed clip, lubricated its sliding faces and reports that it holds the carrier in place. The stated 1298201577, 1298200577 and 1298200677 numbers identify complete lamp assemblies, not this printed child, so they are not assigned. Print with the circular opening toward the bed, use ABS or another heat- and weather-resistant material, verify smooth clip travel and carrier retention, then test every rear lamp before driving.

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.

Replacement rocker cap for the electric-window switch. The creator modeled it after a broken original, reports that it fits, and recommends resin printing because ordinary FDM appearance and durability were unsatisfactory. Preserve the switch mechanism and contacts, confirm free return movement and electrical isolation, and stop using the part if it binds or softens in cabin heat.

Full-size glovebox body measured by hand from an original 107-series part. The creator states that one hole beside the lamp opening is intentionally absent, so transfer and drill that position from the original only after confirming lamp, latch, hinge and dashboard clearances. Use cabin-heat-resistant material and test the box without forcing aged dashboard trim.

Workshop adapter that seals the airflow-meter opening to connect a smoke machine during intake-system leak diagnosis. The creator shows it fitted on a 107-series engine. Use only on a stationary, cool engine with low-pressure diagnostic smoke, protect the airflow meter and hoses from excess pressure, never run or drive the car with the adapter installed, and remove it after testing.

Four-piece printable shell for rebuilding the weathered electrical connector on a 107-series central-locking mechanism cable. The source photographs the failed original, loose terminals, printed assembly and installed connector, and notes that PLA worked for the prototype; PETG, ABS or nylon is preferable for cabin and door-cavity heat. Preserve terminal positions and insulation, disconnect the battery before electrical work, verify polarity and strain relief, and test locking operation before closing the trim.

Cosmetic snap-on cover for an exposed armrest fastener. The source identifies 107-series fitment but gives no production-break or upholstery-colour claim. Use a cabin-heat-resistant material, compare the fastener head and receiving recess, and test gently so the printed clip does not damage aged seat or armrest trim.

Replacement retaining clip for the removable suncover on the 300 SL. The source claims only 300 SL 107-series fitment, so no other engine, trim or model-year application is inferred. Use cabin-heat-resistant material, compare the original clip and mounting interface, and verify secure retention without stressing the cover.

Replacement frame fitted beneath the rubber gear-selector boot to retain it in the centre console. The creator explicitly identifies 107-series SL and SLC fitment and designed it because the original retainer was unavailable. Compare the selector opening and boot lip, use heat-resistant material, and confirm unrestricted selector movement through every position before driving.

Drop-in cup holder designed for the centre-console recess of the creator's 1989 560 SL. It prints without supports and includes a shallow adjacent tray. Fitment is limited to the demonstrated late-production console; compare the recess before printing, keep the holder clear of the selector and handbrake, and verify that containers cannot interfere with any control.

Four-piece conversion set for the early dashboard centre stack: a single-DIN HVAC/radio panel, left and right slider trim, and an ashtray-replacement holder for a USB charger or voltmeter. The creator built and photographed it in an early 450 SL and warns that switch layouts changed over production even though the panel outline may remain similar. Restrict use to the demonstrated early layout, compare every opening and fastener before printing, fuse any added electrical outlet correctly, and retain safe clearance from wiring and HVAC controls.

Replacement knob for the heating and ventilation slider controls. The source explicitly covers 107-series SL and SLC controls and shows the knob fitted at the dashboard vent-control panel. Add a white indicator mark after printing if desired. Use heat-resistant material and verify smooth full slider travel without binding before driving.

Replacement retaining clip for the cabin sun visor. The creator made and printed it for an older 107-series SL and notes that print cleanup may be needed. Use a cabin-heat-resistant material, compare the screw spacing and visor-rod interface with the original, clean the retention opening carefully, and confirm that the visor locks and releases without damaging the headliner.
