Mercedes-Benz SL R107 3D-printable parts

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.
