BMW Z3 E36/7 / E36/8 3D-printable parts

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 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.

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.

Mine got lost, so I decided to make one! Print in PETG or other heat resistant filament. BMW (E46 3 Series, E83 X3) Battery Positive Terminal Base B + - Cover Cap (61138371011) Fuse and insulate any added wiring correctly, secure it from chafe and confirm the circuit remains serviceable.

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.

Four clip-in replacement gear-knob shapes for the BMW E34 and the creator-listed classic BMW chassis. The design was developed around the common BMW latching stem and includes an installed physical example. Confirm the lever's clip profile and preserve full shift travel before driving; the grouped API fitments reproduce only chassis families explicitly listed by the creator.

Replacement black blanking cover for an unused dashboard switch opening on BMW E32, E34, E36 and Z3. The source gives interchange number 51161963979, which BMWFans confirms as black cover 1963979 produced from April 1987; the alternate 51161963987 could not be catalog-confirmed and is intentionally omitted. Check color, opening and switch-bank configuration.

Replacement guide bushing for the seat-drive screw where worn originals cause seat wobble. The source identifies the problem on this vehicle and shows the worn assembly and printed bushing; four are required per seat. Seat removal and disassembly are required, so isolate the battery, observe restraint-system precautions, and verify full travel and secure locking before driving.

Two alternatives for the small centre-console accessory opening: a plain blank and a USB insert. The creator reports exact fit on this generation. BMWFans and RealOEM identify the original plain plug as 51168400712, introduced January 1996; dry-fit before installing any connector and keep wiring fused and clear of controls.

Plain and microphone-opening alternatives for the dashboard switch opening. The creator reports that the cover fits correctly. BMWFans and RealOEM identify the plain cover as 51168104346 and include this generation in its applications. Confirm microphone retention and keep wiring clear of HVAC and control mechanisms.

Plain and USB alternatives for the wider centre-console accessory slot. The creator reports correct fit. BMWFans identifies original cover 51162492136 from January 1997 with this generation in its applications. Dry-fit the chosen insert and secure any connector and wiring before use.

Replacement headlight-switch knob that the creator printed and used after the original disintegrated. The knob body was measured from the original but the decorative cap profile was reconstructed without an original cap, so no BMW component number is assigned. It requires an M5-0.8 nut; verify positive switch operation and retention before driving.

Replacement interior door-handle surround shown as a finished physical print from several angles. Test-fit without forcing the trim, confirm the handle returns freely, and use a cabin-heat-resistant material.

Two-piece housing and lid for the remote-key receiver when fitting a smaller replacement rear-view mirror with a compatible tri-lobe adapter. The creator reports mounting and using the replacement mirror. Secure the receiver and wiring without obstructing mirror adjustment or visibility.

Wear grommet for the Roadster soft-top tension cable. It replaces only the damaged grommet, not the complete BMW tension-cable assembly 54318400951, so that parent number is deliberately omitted. Inspect the cable and top mechanism, and verify unrestricted roof travel before use.

Two-piece cupholder and mounting insert for the rear-console slot behind the handbrake in the creator's 1999 2.5-litre Roadster. The source shows it installed. Bond or fasten the parts securely and confirm handbrake, seat and belt-buckle clearance.

Longer repair guide for the Roadster and M Roadster seatbelt guide, independently remeasured after a shorter design moved in use. The creator reports successful PETG use and shows it installed. This is a trim guide, not a restraint anchor; confirm the belt feeds and retracts freely and never modify the belt or anchor.

Replacement right-side dashboard vent designed to snap into the original opening and reported as an effortless installation. It is the passenger-side vent on LHD cars and driver-side vent on RHD cars. BMWFans identifies the right defroster-nozzle cover as 64228399954 from September 1995. Verify louvre movement, duct sealing and dashboard retention.

Custom blank for routing microphone or charging cable through an unused centre-console button opening in the creator's 2002 car, shown installed. Secure and fuse powered wiring, protect cable edges, and keep controls unobstructed.

Screw-retained sleeve for a broken lower finger on the passenger-seat belt guide in the creator's 2002 car. The installed repair, original damage and break diagrams are documented. It does not replace the belt or anchor; verify smooth belt feed and retraction before driving.

Exact-copy replacement for the upper glovebox latch catch, shown installed. RealOEM and BMWFans identify the separately serviced upper catch as 51161849472 and show it in the glovebox diagram for this generation. Verify the lid latches, releases and sits flush without excessive force.

Caliper-modeled replacement for deteriorated floor plugs in the creator's 1998 car, shown installed and compared with the original. The TPU print was accidentally rain-tested and reported watertight. Inspect the surrounding metal, use compatible sealant only if required, and verify water sealing.

Flexible replacement retaining lanyard for a broken or missing fuel cap tether in the creator's 2002 car, shown installed. No separately serviced BMW number was established for the printed tether. Confirm the cap seals and the lanyard cannot foul the filler neck or flap.

Removable armrest shown physically installed over the centre console. Confirm handbrake, shifter, belt-buckle and seat-travel clearance and remove it if it can interfere with any control.

Replacement housing for the seat-drive mechanism used in both Roadster and Coupe. The creator reports the ABS version has worked for seven years and recommends nylon; STEP geometry is included. Seat removal is required, so isolate the battery, observe restraint-system precautions, and verify travel, locking and fastener torque before driving.
