Mercedes-Benz SL R129 3D-printable parts

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.
