Two-piece repair for the right-hand locking pin/holder used when the retractable luggage-compartment cover is pulled across the cargo area. The creator designed it from the broken component on a 2006 vehicle and separated the base and holder because a one-piece print was too tight to install; clip in the base, then bond the holder to it. Mercedes EPC-style evidence identifies exact child A1648120201 as the right cargo-cover locking pin and maps that same component to W164 and X164. Verify side, colour/trim interface and retention before use.

Three-part retaining tether for the fuel cap, explicitly shown by the creator on an R171 and described as fitting many Mercedes fuel caps. The design comprises a cap ring, flexible cord, and eyelet. The source used ASA for the ring and hard Shore D56 TPU for the cord and eyelet, while noting that approximately Shore A95 TPU may also work. Install all three parts, verify the ring does not interfere with cap sealing or locking, keep the tether clear of the filler neck and hinge, and replace it if fuel exposure, heat, or repeated flexing causes cracks or loss of retention. No other generation is linked because the creator does not identify one and no exact child-component number was established.

Fits SLK / SLC · R171

Two-piece replacement housing for the starter cable connector on a 2006 SLK 350. The creator modeled it after the original housing crumbled, printed it successfully in ABS, and warns that its position under the exhaust manifold exposes it to substantial heat. Use both housing halves, print only in a suitable high-temperature electrical-insulating material, inspect the cable and terminal for heat or corrosion damage before installation, maintain factory routing and insulation clearances, and discontinue use immediately if the print softens, cracks, or allows terminal movement. Fitment is source-backed only for the stated 2006 SLK 350 within R171.

Fits SLK / SLC · R171

Six-piece bracket and spacer set for installing a Hikity 10.1-inch Android double-DIN head unit in a 2005 SLK 350 without drilling the vehicle. The creator replaced an Audio 20 unit, reports that installation was easy, and says the brackets will likely suit SLK 280 variants and the rest of the same R171 generation; no fitment outside R171 is claimed here. The large screen requires removal of the factory cupholders. Print in PETG, ABS, ASA, or another cabin-temperature-capable material rather than PLA, which the creator warns can soften in a hot car. Verify fastener engagement, wiring clearance, screen stability, and unobstructed access to the hazard and Airscarf control panel before driving.

Fits SLK / SLC · R171

Replacement hinge inserts for the power-window actuator switches, supplied as distinct driver- and passenger-side files because the locating pins are different sizes. The creator shows the printed parts with the original switch housing and secures each insert with double-sided tape on its back and bottom surfaces. Use a heat-resistant material, select the correct side, keep adhesive clear of contacts and moving surfaces, and confirm normal switch return and window operation before refitting the door controls.

Fits A-Class · W169

Replacement retaining clip/cover for the front door trim panel. The creator explicitly identifies both the A-Class application and exact child-component number A1697270014; independent genuine-parts listings corroborate it as the left/right front door-card trim clip also used on the B-Class W245, which is absent from the live taxonomy. Verify trim colour and socket geometry against the removed clip, press the panel home without forcing it, and replace the print if the panel is not held securely.

Fits A-Class · W169

Left- and right-hand side guides for the inner shade of the factory lamella sunroof. The creator explicitly describes these as the second-version guides from a 2009 vehicle; do not treat them as universal for other roof systems, years or guide revisions. The files are separate side variants. Compare the original guide profile and orientation before printing, use a heat-resistant low-friction material, test shade travel gently by hand, and discontinue use if the guide binds, sheds debris or interferes with roof movement.

Fits A-Class · W169

Mount set for installing the pictured auxiliary lamps in the front grille. The creator documents cutting the grille, M8 hardware, silicone bonding, bumper-lug anchoring and states that post-2013 facelift fitment is unknown; use only on verified 2003–2012 pre-facelift grille geometry. Check local lighting rules, keep cooling airflow and sensors clear, use weather- and heat-resistant material and corrosion-resistant hardware, and verify secure aim and retention before driving.

Fits Vito / Viano / V-Class · W639

Sturdy adapter ring for fitting aftermarket speakers to the stock front-door or rear-side mounting pattern. The creator reports precise alignment with the factory screw holes and supplies installed source photographs. This is an aftermarket adapter rather than any listed speaker assembly, so no speaker OEM number is assigned. Verify speaker diameter, depth, window and trim clearance, seal against rattles and moisture, and secure wiring away from moving mechanisms.

Fits Vito / Viano / V-Class · W639

Glue-on repair tabs for broken mounting points on the front grille. The creator documents superglue installation and an optional filament pin through drilled 1.5–1.75 mm holes; photographs show the repair installed. These prints reproduce repair fragments rather than the grille assembly, so no grille OEM number is assigned. Verify the exact break, use weather- and heat-resistant material and adhesive, and confirm the grille is retained clear of cooling airflow and moving parts.

Fits Vito / Viano / V-Class · W639

Flexible expansion dowel for the rear number-plate mounting holes, designed so scaling can compensate for enlarged corroded openings. Source photographs show the loose child and installed location. Use weather-resistant TPU, assess and repair corrosion separately, scale conservatively, use compatible screws, and confirm the plate is secure without distorting the tailgate skin.

Fits Vito / Viano / V-Class · W639

Flexible 42 mm plug for sealing body openings in the windscreen-wiper compartment. The creator warns that rigid filament will not fit; source photographs compare printed and original plugs and show the installed locations. Print only in suitable TPU/flex, verify every opening size and drainage path, and confirm the plugs seat fully without trapping water or wiring.

Fits Vito / Viano / V-Class · W639

Flexible protective cap for the front windscreen-wiper arm nut, print-tested by the creator in 95A TPU and shown installed. Match the spindle and arm version, use UV-, weather- and washer-fluid-resistant flexible material, seat it without contacting the moving arm, and confirm full wiper travel and retention after wet-weather operation.

Fits Vito / Viano / V-Class · W639

Two-piece flexible gasket for the rear-window wiper shaft. The creator explicitly describes it as a temporary fix because typical printable TPU is harder than the original rubber; installation requires removing the rear wiper motor. Use only as a temporary non-equivalent seal, match the exact shaft and glass interface, avoid loading or scratching the glass, and verify sealing, motor alignment and free wiper movement.

Fits Vito / Viano / V-Class · W639

Flexible replacement tether for the fuel filler cap, created after the original tether failed and shown installed on the filler door. Print in fuel-, UV- and weather-resistant flexible material, preserve the cap sealing surfaces and venting, keep the tether clear of the neck and hinge, and confirm the cap still seals and locks normally.

Phone holder for the factory mounting point beside the steering wheel, designed around an iPhone 6 with a silicone case. The source includes an installed photograph and author STL/OBJ geometry. Verify device dimensions and the original mounting interface, use tough cabin-heat-resistant material, and confirm the phone cannot obscure instruments, interfere with steering or airbags, or detach under braking.

Fits Vito / Viano / V-Class · W639

Replacement wing nut used on several battery and storage-compartment covers. Source imagery shows the installed fastener location and the loose printed geometry. Match the original thread and cover version, print in tough cabin-heat-resistant material, do not force a mismatched thread, and tighten only enough to retain the non-structural cover without cracking it.

Fits Vito / Viano / V-Class · W639

Replacement retention clip for the bonnet support strut. The author supplies printable STL and editable STEP geometry plus a source photograph of the physical clip. Use engine-bay-temperature- and weather-resistant material, compare the strut diameter and mounting profile, and confirm the strut is retained when stowed without weakening or interfering with bonnet support or latching.

Fits Vito / Viano / V-Class · W639

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.

Fits Vito / Viano / V-Class · W639

Replacement frame and cover for the vanity mirror in the sun visor. The source shows the printed frame holding a mirror insert and the supplied author geometry. Reuse only safe, intact mirror material, smooth every edge, use cabin-heat-resistant material, retain the frame without stressing the visor, and confirm the cover closes securely and cannot fall into the driver field of view.

Fits Vito / Viano / V-Class · W639

Replacement wardrobe-door locking tab for the Marco Polo camper interior. The creator supplies photographs comparing the printed and original pieces and shows the replacement installed. Print in tough cabin-heat-resistant material, match the wardrobe version and door alignment, and confirm the door remains securely latched through repeated opening, closing and road vibration before carrying contents.

Fits Vito / Viano / V-Class · W639

Replacement hook for the kitchen rail in a Marco Polo camper interior. Source photographs show the printed hook installed on the rail and carrying a light bag. Match the rail profile before use, print in tough cabin-heat-resistant material, deburr every sliding/contact face, and limit use to lightweight loose items that cannot become projectiles while driving.

Fits Vito / Viano / V-Class · W639

Smartphone holder that mounts into the original SAP V3/V4 Bluetooth cradle beside the steering wheel using the cradle connector and three factory mounting holes. The creator designed it around a Samsung Galaxy S5 with S-View cover; verify the phone and cradle dimensions, keep the display clear of instruments and controls, route charging safely, and confirm the device cannot detach or obstruct steering, airbags or driver visibility.

Fits Vito / Viano / V-Class · W639

Blank insert for the MP3-button position in the center-console switch panel. The author identifies the exact chassis and supplies the printable geometry, but does not establish applicability to every switch-panel or equipment variant; compare the opening before printing.
