Interior — 3D-printable Mercedes-Benz parts

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.

Direct-replacement manual seat adjustment handles supplied as separate left- and right-hand files. The creator designed them for a 2007 vehicle and identifies the right-hand component as original part A1699190661; Mercedes genuine-parts and PartSouq listings corroborate that number as the right-side seat-adjustment lever. The OEM number applies to the right-hand file only. Use a tough, heat-resistant material, compare the mounting socket and travel with an intact handle, and verify that the seat locks positively in every tested position before driving.

Replacement lever made after the originals broke on W203/S203 seats. The creator reports PLA loosening after sun exposure and successful use in PETG. Compare the lever shaft and seat-control version, use tough cabin-heat-resistant material, fit without forcing the switch and confirm every seat adjustment operates normally and the lever remains secure; this file does not replace structural seat or restraint hardware.

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.

Working replacement trim plug for the rear-seat ISOFIX anchor opening, derived by the creator from a 3D scan of the factory cover. The creator states that the scan is not perfect; compare the upholstery opening and verify secure seating. This is only a removable trim cap: it must not obstruct, modify or carry load from the ISOFIX anchor, and it should be removed before attaching a child restraint.

Cosmetic plug for closing the exposed holes left after removing the armrests from individual V-Class seats. The creator explicitly tags this chassis and supplies the printable child geometry and multiple CAD source views, but gives no material, seat-version, colour or long-term retention details. PETG, ABS and nylon are listed only as conservative tough cabin-heat-resistant choices. Compare the exposed seat hole and plug profile, fit without forcing the seat trim, and confirm the plug remains secure and does not interfere with seat adjustment or restraint hardware.

Replacement locking pin for a seat armrest, redesigned with a toothed arc and used successfully by the creator with M3 and M4 nuts and screws. Compare the original geometry and armrest version, use tough wear- and cabin-heat-resistant material, secure the hardware against loosening, and verify the armrest locks and releases repeatedly without affecting the seat or belt before driving.

Trim cover for the upper seat-belt height-adjuster anchor. Source photographs show the printed cover installed over the factory adjuster; it is cosmetic and must not carry belt load. Use tough cabin-heat-resistant material, preserve unobstructed adjuster travel, never cover damage or alter the belt, anchor or mechanism, and confirm the belt retracts, adjusts and locks normally after fitting.

Replacement handle for adjusting the front-seat position after the creator’s original handle broke. The source explicitly identifies the first-generation SUV and includes a photograph of the printed handle installed beneath the seat. This is a convenience-control handle, not a structural seat or restraint component; compare the socket and lever travel before use.

Replacement left retaining hook/clip for the rear trim panel of a front seat. The creator identifies the exact child as A2089130172 for the 208-series and states that the model can be mirrored in the slicer for the opposite side. Mercedes official evidence calls A2089130172 the left hook, and PartSouq search evidence corroborates its front-seat-trim function. The OEM number applies only to the supplied left-side geometry; no right-side number is inferred for a mirrored print. Seat type, upholstery and option differences can affect fit, so verify by VIN and compare the original before fitting.

Driver- and passenger-side replacement lever files for a 126-series electrical seat switch. The source identifies the function and fitment but provides only a photograph of the original child component, not a printed installation. Compare the switch version, shaft and lever direction exactly, use tough cabin-heat-resistant material, and verify every seat movement stops on release without a lever sticking or fouling the trim.

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.

Bolt-on replacement handle for broken manual seat-adjustment levers. The creator explicitly designed and photographed it for both 116-series and 123-series cars, states that it can be used at all four handle positions, and notes that side height adjusters accept one screw while the front adjusters use two. The demonstrated part was printed in PETG, sanded and buffed, then fastened through the surviving metal lever with screws and nuts. Remove only the remains of the failed grip, preserve the original lever, deburr all holes, use secure low-profile hardware, and confirm full adjustment and locking travel before driving.

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.
