Flexible replacement mount for the diesel air-filter housing, printed and reported satisfactory by the creator. The exact serviced child is Mercedes A6110940385, independently corroborated as an air-filter housing elastomer mount for W203 C200 CDI, C220 CDI and C270 CDI applications; A6110940085 appears as a related alternative reference but is not assigned. Use engine-bay temperature-, oil- and ozone-resistant elastomer, compare the original mount and engine application, fit both required mounts and verify the housing remains secure without transmitting abnormal vibration.

Two internal replacement parts for the gear-selector mechanism. The creator identifies exact chassis fitment, supplies a physical source photograph and states that one O-ring is required to retain the assembly. The archived files were 3MF containers carrying misleading STL extensions and are preserved for upload with corrected .3mf filenames. Compare both original profiles and the selector version, use tough cabin-heat- and wear-resistant material, fit an oil-compatible O-ring of the correct size, and verify every gear position, detent, indication and interlock repeatedly with the vehicle stationary before road use.

Fits Vito / Viano / V-Class · W638

Standard- and loose-fit replacement grommets for mounting the hydraulic self-levelling suspension oil reservoir on estate cars. The creator identifies the exact child as A1299971681. These grommets support only the reservoir, not a suspension load path. Use oil-, heat- and vibration-resistant flexible material, match the mounting hole and reservoir pin, and inspect for leaks and secure retention after installation.

Fits E-Class · W124 / S124 / C124 / A124

Replacement grommet through which the radiator lower locating prongs pass. The source establishes 124-series fitment but provides only model imagery. This grommet isolates and locates the radiator; it is not a structural vehicle mount. Compare the original opening and radiator pin, use engine-bay heat-, coolant- and vibration-resistant flexible material, and confirm secure seating, fan clearance and leak-free hoses after installation.

Fits E-Class · W124 / S124 / C124 / A124

Direct replacement for the lower condenser mounting grommet identified by the creator as A2019970381. The source model intentionally simplifies fillets and tightens the fit for printing. Compare the original grommet and condenser pin, use heat-, weather- and vibration-resistant flexible material, and confirm the condenser is retained without metal-to-metal contact or stressed refrigerant lines.

Fits E-Class · W124 / S124 / C124 / A124

Replacement clip used in pairs to secure the lower engine wiring harness to the engine block; the creator notes that the same size also appears elsewhere. Exact routing varies with engine and model year, so compare the original clip and mounting point rather than inferring other positions. Use engine-bay heat-, oil- and vibration-resistant insulating material, avoid sharp wire contact and confirm the harness cannot reach hot or moving parts.

Fits E-Class · W124 / S124 / C124 / A124

Two-piece replacement shaft set for the mechanical speedometer drive. The creator printed it in PETG with a 0.2 mm nozzle, reports about 1,500 km of successful use, and notes that axle sanding may be required. The cited EPC number describes the complete speedometer-drive component and is not assigned to these printed internal pieces. Match the transmission drive version, avoid altering tooth geometry, and verify accurate speed indication and leak-free operation.

Fits 190 Series · W201

Spacer ring developed to retain a near-match replacement dust boot on a 126-series rear self-leveling-suspension hydraulic strut when the original boot is unavailable. Source photographs show the physical ring and boot installation. This is a protective-boot adapter only, not a suspension load path. Match the replacement boot and strut dimensions, use oil-, weather- and fatigue-resistant material, and inspect hydraulic lines, clearance, leaks and boot retention before returning the car to service.

Fits S-Class · W126 / C126

Flexible downward-facing bell for the fuel-tank vent line, recreated after rodent damage on a 300CD/T/D application. The creator printed it in flexible filament at 100% infill and describes a friction fit on the black 90-degree elbow. Use fuel-vapour-compatible material, preserve an open vent path, secure the bell against loss and stop if tank venting, odour or leakage changes.

Fits W123 Series · W123 / S123 / C123

Replacement lid modelled for the fuse box on a 230E. Other engines are explicitly untested, so fitment is restricted to the demonstrated configuration. Reuse the original gasket and fuse-card insert as instructed, print in engine-bay heat-resistant material, verify full sealing and latch engagement, and never install a warped lid that could admit water or contact fuses.

Fits W123 Series · W123 / S123 / C123

Replacement 4 mm plastic locking pin for electrical sensor connectors and the Stromberg 175 carburettor valve connector. The creator demonstrates the printed pin with the original sensor fittings. Match the connector body and pin diameter exactly, use engine-bay heat- and fuel-resistant material, route wiring without strain and confirm the connector cannot loosen or short before operating the engine.

Fits W123 Series · W123 / S123 / C123

Replacement automatic gear-selector linkage bushing printed for a degraded original on a 123-series car. The creator shows the part at the linkage and notes that a 1/4-inch E-clip can replace a missing retaining clip. Use a wear-resistant material, retain the linkage securely, then verify every selector position, positive Park engagement and neutral-start behavior with the parking brake applied before driving; stop use if the linkage binds or develops play.

Fits W123 Series · W123 / S123 / C123

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.

Fits SL · R107

Replacement bushing modeled from the original linkage part on a 1974 US-market 2002 and physically printed and used by the creator. The supplied geometry is 26 mm outside diameter, 12.5 mm bore and 16 mm hat diameter. The original is rubber; use a suitable flexible material for original-like compliance, or note that a rigid ABS print deliberately produces firmer shift feel. The catalog contains several production-date-dependent linkage bushes and joints, and the source does not identify which serviced child number it reproduces, so no OEM number is assigned. Confirm dimensions, linkage articulation and secure retention before driving.

Fits 02 Series · Type 114 / E10

Two replacement retainer geometries for repairing broken attachment tabs on the BMW X1 E84 engine air-filter housing. The creator links the original repair write-up and supplies physical comparisons, loose parts and installed engine-bay views for both shapes. The printed pieces repair features of the larger air-filter housing rather than reproducing a separately serviced BMW child component, so no housing parent number is assigned. Print in PETG as documented or a higher-temperature engineering polymer, fasten exactly as shown, and verify intake sealing, bonnet clearance and retention after heat cycling.

Fits X1 · E84

Thickened replacement cover for the BMW E31 heater/water-valve assembly, physically printed by the creator and reported to resist under-bonnet heat. The design uses 10 x 2 mm neodymium magnets against the valve fasteners. BMW catalogs identify the original separately serviced cover as 64111383499 for E31 840i/840Ci, 850i/850Ci and 850CSi; genuine production ended in 2015 with no documented supersession. Use high-temperature material, secure the magnets, and confirm hose, wiring and bonnet clearance after installation.

Fits 8 Series · E31

Dual catch-can mounting bracket designed by the creator for the S63TU engine bay in the BMW F13 M6 and F10 M5. The creator links an installation video for the twin-turbo M6 setup, providing physical-use evidence beyond the preserved CAD render. Print in a heat-resistant engineering material such as nylon, keep clear of hot or moving components and hoses, and inspect retention after initial heat cycles. This is an aftermarket accessory with no original BMW component counterpart, so no OEM number is assigned.

Fits 5 Series · F07 / F10 / F11 / F18 · 6 Series · F06 / F12 / F13

Protective cap for the top of the front strut mount on BMW E28 models. The creator printed it in PETG and road-tested the design for 5,000 miles before release. BMW catalogs identify the equivalent 28.5 mm covering cap as 31331124335; do not confuse it with the separate dust-protection collar 31331110196. Verify top-nut and mount dimensions before use.

Fits 5 Series · E28

Replacement throttle-body linkage/cable nipple for the M10-powered BMW E28 518i; two identical pieces are required in the catalog assembly. The design is based on an original part and includes print-orientation guidance. BMW number 13541286378 is cataloged specifically for E28 518i M10 applications and selected M10-powered E30 models, not every E28 engine.

Fits 3 Series · E30 · 5 Series · E28

Adjustable clutch-pedal stop body for manual-transmission BMW E28 and other listed classic BMW chassis. Assembly requires an M10 screw, two M10 nuts, a 40 mm washer and a genuine-style rubber cap. Adjust only far enough to remove excess pedal travel while preserving complete clutch disengagement, then lock the nuts securely and re-check operation before driving.

Fits 3 Series · E30 · 3 Series · E36 · 3 Series · E46 +4

TPU clutch-stop set in 10, 12, 14 and 16 mm heights for manual BMW F3x models; the creator reports the 16 mm version installed with the factory clutch. Use the specified material, inspect layer adhesion and fit, and stop if the part interferes with safe service or pedal operation.

MAF adapter for a 335d to a 4" flange cone filter. Takes the oval and turns it into a circle for mounting a cone filter. I used RTV silicone to attach it to the MAF (it's a very tight fit), once it sets clamp on your filter. Designed so the air is funneled in... Use the tool only for the documented engine or transmission, keep it square and follow the BMW service procedure and torque values.

This is a fix that I made for my 2007 BMW 320D air intake back in 2014. The M47N2 engine air intake hose has rubber ends which start to break over time, so instead of spending >30€ on a new OEM part (13717795284), I decided to make a fix of my own, as I had a 3D printer at home at that time. People keep asking me for the STL, and since I no longer have my own server, I decided that it's time to upload it here. NOTE: it's a tight fit so you'll most likely have to remove the whole 3 connecting parts of the intake as a single unit when trying to get to the engine (only 4 screws though, so it's not a big deal). Use the tool only for the documented engine or transmission, keep it square and follow the BMW service procedure and torque values.

Fits 3 Series · E90 / E91 / E92 / E93

80 mm intake adapter for vacuum or smoke leak testing on the E46 M54B22, designed around a standard automotive valve and physically demonstrated on the engine. Use only at low diagnostic pressure, keep foreign material out of the intake and remove the adapter before starting or driving the vehicle.
