Mechanical — 3D-printable BMW parts

Three-piece service-tool set for BMW N42, N46, and N46T engines: intake camshaft lock, exhaust camshaft lock, and the creator's strengthened M8-bolt VANOS gear counter-holder. The creator reports using the tools repeatedly and revised the counter-holder for the specified tightening procedure. This is an engine-specific workshop aid, not a substitute for BMW service information: inspect every print before use, follow the applicable repair procedure and torque sequence, and stop if any cracking or deformation is visible.

36 mm, half-inch-drive oil-filter housing socket physically tested on the M47 diesel engine in a BMW E87 1 Series. The creator printed it at 90% infill, shows it seated on the filter cap, and reports successful use. Use a tough material, inspect the drive and hex surfaces before use, and replace the print if it shows cracking or rounding.

Two-piece intake opening developed and physically fitted to the airbox of a BMW F20/F21 1 Series. The creator states that it is intended to add intake sound, not power; the cutting profile and finished insert are both included. Keep the factory filter path intact, use an engine-bay-temperature-resistant material, de-burr the airbox opening, and inspect the installation for secure retention and contamination paths before running the engine.

Round and splined clutch-alignment tool variants designed for BMW N55 cars with the GS6 manual transmission. The creator printed the tool for a 2015 F22 M235i clutch replacement and verified the splined version during installation. Source fitment also names N55 E82, E9x, F3x, F10/F11, and F22/F23 cars. Use only on the specified engine/transmission combination, compare pilot and spline dimensions before use, and do not treat the printed tool as a torque-bearing service tool.

Dust cap for replacement-style E30 front strut mounts with an approximately 31.3–32 mm opening, where the original cap no longer fits. Test-print the retaining ring and adjust scale for the measured mount before making the full cap.

Printed cap wrench for the 76 mm, 14-flute oil-filter housing associated with BMW 11421715960. The creator physically demonstrates the tool and lists E30, E36, E46, E34 and Z3 applications; confirm cap size before applying torque.

Replacement front-strut top dust cover for E30 cars fitted with Koni adjustable dampers where the stock cover does not fit. The creator printed and used the PETG version; confirm adjuster clearance and cap retention.

Screw-on protective cover for exposed E30 front wheel-bearing spindle surfaces during restoration, washing, blasting, painting or storage. It is physically shown on the spindle and is removed before wheel-bearing assembly.

Replacement beauty cap for M50, M52 and M54 engine-cover fasteners, physically shown on the engine. BMWFans identifies the exact component as cap 11121726089 and confirms E34, E36, E38, E39, E46, E53, E60/E61, E65/E66, E83, E85 and Z3 applications. Use engine-bay-rated material and keep it clear of hot or moving parts.

14 mm hex-drive hand tool for the star-shaped cell caps on the original battery in a 1999 E36. The source shows both the printed wrench and matching battery caps. Use only with the battery isolated, wear eye protection, and do not short the terminals.

Service driver sized to install 168 mm differential output seals to the original depth on four-cylinder E36 and creator-listed Z3 applications. The source shows the physical tool on the differential. Use with a flat striking plate, measure seal depth, and inspect the seal lip before assembly.

50 mm inner-diameter service sleeve for pressing output-flange seals out of the 168 mm differential on a 1995 E36 318ti. The source shows the physical tool and flange. Support the housing correctly, keep the tool square, and do not reuse a damaged seal.

Protective cap for the upper front strut bearing on a BMW E36, physically shown printed and installed in the engine bay. Use engine-bay-rated material and confirm it clears the strut brace, nut and suspension movement.

Four-piece E36 bumper-inlet duct inspired by the Dinan layout and physically shown installed between the bumper opening and air filter. Print in heat- and impact-resistant material, bond the sections securely, and verify filter, fan, belt, water-ingress and road-clearance conditions on the exact car.

I used it for my BMW E46 and it is very sturdy. You can use a 32mm Hex Nut or a 1/2" square wrench to open the oil filter cap. The Tool on the picture was an earlier smaller version but it broke. Use the specified automotive-grade material, keep the tool square and inspect the serviced component before reassembly.

I designed this valve shim placement tool to aid in my recent valve adjustment on my 2004 BMW E46 M3. After viewing the picture of this special tool online, I decided it wasn't worth the money to order one, so I purchased some magnets and printed one instead. The magnet I used is a 8mm(0.315") Diameter x 3mm(0.118") Height, and was embedded into the base during the printing stage. I used the color change feature of PrusaSlicer to stop the print before the top layer and inserted the magnet. I printed both parts out of PETG and glued them together with cyanoacrylate. The tool was tested on my engine and worked perfectly. I even did the hard to reach rear valves with this homemade tool. Use the specified automotive-grade material, keep the tool square and inspect the serviced component before reassembly.

I used this tool to remove the crankshaft seal on the M54 engine timing cover. To use it properly, you must place the removal tool from the inside of the timing cover, pushing the seal out towards the outside of the timing cover. Use a mallet and some patience to get it out. Use the specified automotive-grade material, keep the tool square and inspect the serviced component before reassembly.

This is for installing a new center support bearing on your E46 driveshaft without risking damaging the bearing. Simply apply some lubricant where the bearing will seat onto the driveshaft and slide bearing on. Then use the tool to hammer in the bearing. It is easier to do with 2 people or if you can stand up and balance the driveshaft with your legs (Ask me how I know). Use the specified automotive-grade material, keep the tool square and inspect the serviced component before reassembly.

Replacement air-intake suction tube for 1999-2001 E46 M52 models, physically installed by the creator. BMWFans, RealOEM and Hubauer cross-confirm genuine BMW component 13711438768 for the matching E46 320i/320Ci, 323i/323Ci and 328i/328Ci applications. Print in a heat-resistant engine-bay material and verify sealing and clearance.

This is a nut for the engine cover as seen in the second image. It works for e46 316i,318i and 320i, possibly for other models that have the same nut. Note: you will need an O-ring or rubber washer (⌀10mm) to prevent unscrewing due to the engine vibrations, the original nut has one too. You'll need ABS filament or PET-G, PLA filament will break after a couple of months. Print Settings Printer Brand: Artillery Printer: Artillery Hornet Rafts: Yes Supports: No Resolution: 0.2 Infill: 25 Filament: ABS or PET-G Notes: minimum 3 perimeter for Vertical shells Category: Automotive Use the specified automotive-grade material, keep the tool square and inspect the serviced component before reassembly.

Sixteen-flat 86 mm service wrench for the oil-filter housing on E46 models with the N42B18A engine, designed for a 12.5 mm square drive. The creator shows the physical tool on a ratchet. Use a strong heat-resistant material, keep the wrench fully seated and follow the BMW service torque for the housing cap.

Replacement oil-sump drain-plug access cover for E46 and Z4 E85/E86 undertrays. The creator corrected the screw-hole location and removed reinforcement that caused the physical print to warp. Use an underbody-rated material and verify screw retention, exhaust clearance and complete undertray seating.

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.

Two-piece M54 engine air-intake duct physically fitted to the E46. BMWFans, RealOEM and Hubauer cross-confirm genuine BMW intake tube 13717509118 for the matching M54 and M56 applications. Use a heat-resistant engine-bay material and verify air-box sealing, bonnet clearance and freedom from belts and fans.

This tool perfectly aligns the clutch friction plate for a BMW E90 325i with dual mass flywheel and self adjusting clutch. On the gearbox side of the tool there is a 7.1mm dia hole so that it can be tapped to M8. I recommend printing in PLA with 100% infill. Use the tool only for the documented engine or transmission, keep it square and follow the BMW service procedure and torque values.

Clutch alignment tool for BMW E90 - engine type n47tu - place some tape around the spindle on the tool to make a firm fitting. Custom designed in TinkerCAD, whipped it up in about 15 minutes after googling the dimensions and worked great!!! Originally bought a kit with multiple sizes of spindle and none of the sizes supplied fitted, so, 3D printed this instead and worked better than spending £25 at my local auto-parts dealer for the kit!! 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.

BMW Toolkit screwdriver. I designed this for E90 toolkit, as they stopped supplying these in the trunk after E46's. I spent ~$10 for a Phillips/flathead screwdriver from an online OEM supplier. This vehicle uses solely Torx fasteners, so a Phillips/flathead does me no good. This design allows you to use an off the shelf 2" long 1/4" bit extender. Then you can add whatever bit you'd like. Such as any size Torx bit, any size Phillips, or a flathead. It doesn't quite fit in the toolkit, some trimming would be required as the extender is thicker than the stock neck. However it will fit nicely, and the trimming is easy. The extender is a friction fit, but using an 0.2[mm] nozzle, it is TIGHT. It is also worth noting that this screwdriver has a 10mm box wrench on the bottom, and an 8mm box wrench on the top, but you have to remove the extender to use that one. Replaces BMW PN 71111179629 Shoul Use the tool only for the documented engine or transmission, keep it square and follow the BMW service procedure and torque values.

A little tool I printed to turn those pesky panel locks on my BMW E90 without instead of marring the edges with a big screwdriver. Use the tool only for the documented engine or transmission, keep it square and follow the BMW service procedure and torque values.

Socket for removing oil filter from BMW N52 engine. Adapts to 32mm 6 or 12-point socket. Likely works on other BMW engines as well - I just don't know which ones. I printed out of PETG and had no issues. Use the tool only for the documented engine or transmission, keep it square and follow the BMW service procedure and torque values.

This is clutch alignment tool for BMW self-adjusting clutch. I used it on 2007 BMW E93 with M57 engine, but it could be used on other BMWs with SAC. You will need M6 bolt to use this tool. I print it with 50% infill using PETG, but PLA should work just fine, as you shouldn’t need much force to pull the tool out if you installed and torqued everything correctly. It has been printed on Prusa MK3S printer. Use the tool only for the documented engine or transmission, keep it square and follow the BMW service procedure and torque values.

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.

Use ABS preferably but it wont get that hot up top where this print is located so anything will work 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 centering tool designed for the precise installation of a SAC clutch disc between the flywheel and the pressure plate on a BMW E90 from the year 2011. Due to its adaptable design, the tool may also be compatible with models from earlier or later production years. To assist with model adjustments or integration, a STEP file of the tool has been provided. The tool was 3D printed using PLA+. Standard PLA should also be sufficient, as the component is not subjected to significant mechanical stress during use. After successfully mounting the preloaded SAC pressure plate, the centering tool must be removed before installing the transmission. This can be done by pulling it out using a screw or a pair of pliers. Use the tool only for the documented engine or transmission, keep it square and follow the BMW service procedure and torque values.

Replacement outer fuel-filter clip designed for a 2015 F30 328d and reported by the creator to have remained installed for more than a year. Use the specified material, inspect layer adhesion and fit, and stop if the part interferes with safe service or pedal operation.

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.

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.

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.

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.

Clutch center tool for BMW M52 (and other) motor This tool is needed to mount and center the clutch, you can't used standard tool. Work perfectly on my 1998 528i e39 Creator reports successful use on a 1998 E39 528i. Verify dimensions against the original part and confirm full operation before regular use.

Rear wiper gear BWM E60 Creator supplies physical comparison evidence. This rear-wiper part is for the E61 Touring body, not the E60 sedan. Verify dimensions against the original part and confirm full operation before regular use.

3 pin tool for rewinding rear BMW brakes. I designed the tool to work with a G30, but I think it will work with other BMWs models. The tool is reversable and allows you to either use the triangular pattern for best fit, or the head of the screws. Note: Do not attempt to use without screws installed, it will just shear off the triangular pieces. The design uses #8 x 32 x 1/2" allen head cap screws. For printer settings, beef up the perimeter to 8 and use 50% triangle infill for added strength. Basic PLA did the job. I used the tool successfully to complete a brake job, and redesigned it to improve strength and fit. Simply use a 3/8 ratchet and short extension, then turn clockwise and apply downward pressure. Depending on how tight your calipers are you may only get one use from these, but for a DIY job it works without buying any special tools to compress the caliper. This creator-designed three-pin adapter was successfully used on a G30 rear brake and then strengthened. Install all three specified #8-32 cap screws before use; use a 3/8-inch ratchet and short extension, turn clockwise with controlled downward pressure, inspect the print continuously, and discard it at the first sign of cracking or deformation. Follow the applicable BMW repair procedure and independently support the vehicle; this printed service aid is not an OEM tool.

Service wrench for the notched BMW fuel-tank screw cap used on E46, E60/E61, E63/E64, E65–E68, E83 and E53 vehicles. The creator tested the same interface on an R53 MINI and identified BMW screw cap 16116762417; BMW catalog cross-reference independently confirms that cap across the listed BMW chassis. The printed wrench is not the screw cap itself, so no OEM number is assigned. Use a stiff engineering polymer, hand tools only, and replace rather than reuse any visibly damaged print.

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.

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.

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.

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.

Workshop gauge for checking the center-to-center distance between the front strut towers on early 1966-1967 02-series bodies. The creator physically demonstrates the tool and cites a target of 996 ± 1 mm, measured from the indicated prism edge. This is a diagnostic aid, not a structural repair fixture or substitute for the BMW body-repair manual. Verify the specification against documentation for the exact body before acting on a reading; no vehicle component OEM number is applicable.

Open-sided wrench for removing and installing the plastic retaining nut around the hazard switch without plier damage. The creator physically demonstrates the wrench with the switch and recommends the stiffest suitable material because the clearance slot permits some flex. The title's 61311356193 identifies an early complete hazard switch, not the printed tool or its nut, so it is not assigned as an OEM number. Switch design varies by production date; use only light hand torque on the plastic nut and confirm jaw fit before turning.

Eccentric 48 mm funnel shaped to clear the surrounding structure at the windshield-washer reservoir opening. The creator shows the physical funnel seated in the fill neck from two angles and designed it to print support-free. This is a service accessory rather than the reservoir, filler neck or cap, so no parent number is assigned. Confirm the neck fit before pouring and keep debris and incompatible fluids out of the washer system.

Forty-millimeter funnel shaped for the windshield-washer filler opening. The creator shows the physical funnel seated in the fill neck from two angles and designed it to print support-free with the larger end upward. This is a service accessory rather than the reservoir, filler neck, or cap, so no parent component number is assigned. Confirm the neck fit before pouring and keep debris and incompatible fluids out of the washer system.

Replacement access cover for the oil-drain opening in the engine-compartment underbody screening, physically shown loose and installed by the creator. BMW catalogs identify this child cover as 51757261712, item 5 in the underhood-shield diagram; it is used on X3 F25 and X4 F26 applications, so both live generations are linked. The printed design uses lower U-nuts and hex screws rather than the original fastening method. Print in PETG or a higher-temperature engineering polymer, confirm the panel variant and VIN, and verify secure retention and clearance before driving.

Two-piece replacement dust cover for the steering-gear input shaft. The creator designed it specifically for the first-generation X5 steering rack and shows the printed cover installed around the shaft without removing the steering assembly. Print in a heat-resistant, tough material, secure the two halves as shown by the source, and verify full steering travel, shaft clearance and attachment security before driving. BMW does not catalog this input-shaft cover as a separately serviced child part, so no OEM number is assigned.
