Mercedes-Benz S-Class W140 / C140 3D-printable parts

Original-style and gusset-reinforced replacement variants for the sprung latch inside the center-armrest storage cubby, with creator-stated fitment for 1992–1999 vehicles. The creator also states that mirroring the geometry makes it work for the glove-box latch in the same generation. The source photograph shows the physical latch mechanism and child piece. Independent inspection found the gusseted STL non-watertight, so repair and validate that mesh before slicing. The author reports that commissioned ABS versions lasted about 18 months despite embedded steel wire and changed to SLM 316L stainless steel for expected long-term durability. If printing in polymer, use a tough cabin-heat-resistant material, keep a spare, and verify reliable spring engagement and positive latching before use. Work over a clean surface to avoid losing the original spring; a replacement spring may require a carefully filed groove in the post.

Four-piece left/right replacement retainer set for the power-seat switch panels, explicitly designed as a direct replacement for a 1990s S420. The source photographs show the physical panel assemblies and installed retainers. Independent mesh inspection found three of the four preserved STLs non-watertight, so repair and validate the sliced geometry before printing. Compare side and switch-panel version before use, print in a tough cabin-heat-resistant material, retain the original fasteners, and verify that the panel is secure without restricting any seat control or trapping wiring.

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.

Two-piece retaining clip and screw cover for the cabin sun visor. The creator made it for a 1989 300E and explicitly states W123, W124, W126, W140 and W201 fitment, while noting that it does not carry electrical contacts for illuminated vanity mirrors. Print the main clip and locking cover in the documented orientations, use cabin-heat-resistant material, compare the screw position and visor profile, and confirm secure retention and free release before driving.
