E92 Seat-Belt Presenter Extension Hook
This model replaces the chrome cap of the BMW coupe E92 extender arm with a hook that grabs the seatbelt successfully much more often than the original design. Designed to be a near perfect fit with the OEM shape. I recommend printing in ASA or ABS for the high temperatures in a car. The OEM piece easily comes off with a pry tool, then you can attach the 3d printed models with a strong double sided adhesive ( Confirm normal seat, belt and presenter movement and keep the printed part outside the restraint load path.

Rear Seat-Back Upper Hook
Replacement upper hook bonded to the rear seat-back trim shell. The creator modeled it from a 3D scan of the original F16 component, physically compared the printed replacement with the original, and later corrected the upper section for proper attachment. Mirror the supplied file for the opposite side. Use a heat-resistant, tough cabin-suitable material, verify the hook orientation and seat-back shell geometry before bonding, and keep adhesive and the printed part clear of seat latches, belts, airbags and folding mechanisms.

Late Front-Seat Rail Nut Cap
Replacement front-seat rail nut cap for early cars from September 1985 onward and late-model E30, copied from and physically compared with the original. BMWFans confirms covering cap 52101941999.

Seat-Drive Housing
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.

Seatbelt-Guide Repair Sleeve
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.

Extended Seatbelt-Guide Repair
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.

Seat-Rail Guide Bushing
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.

Trunk Child-Seat Anchor Cover
Replacement cover for a luggage-compartment child-restraint anchor, physically shown installed by the creator in a 2010 X3 E83. BMW catalogs identify the anthracite/black cover as 51473405879, item 12 with three per vehicle; grey 51473418987 and sand-beige 51473418986 are distinct trim variants and are not assigned. Confirm the interior color and VIN, and verify the cover clips securely without obstructing access to the restraint anchor.

Under-Seat Subwoofer Brackets
Pair of compact brackets for hanging a JBL BassPro Nano under the rear-seat frame where the optional amplifier is not installed. The creator printed two in PETG at 50% infill, fastened them with the subwoofer's original screws, and shows the installed unit and bracket locations. Confirm the vehicle lacks the conflicting amplifier, protect wiring, use thread-safe fasteners, and verify seat movement, ventilation and secure retention before driving.

Rear-Seat ISOFIX Opening Cover
Replacement black trim cover for a broken rear-seat ISOFIX anchor opening, physically shown installed by the creator on a 2012 BMW X1 E84. BMW E84 rear-seat catalogs identify the black separately serviced cover as 52207118674, item 9 with four per vehicle; Hubauer documents supersession to 52207332435. Beige 52207152210 and oyster 52202993792 are distinct color variants and are not assigned. Match black trim and verify the cover clips securely without obstructing access to the child-seat anchor.

Adjustable Rear-Seat Side-Cover Pair
Left and right body-side angle covers for the adjustable/split rear-seat configuration of the BMW E32, physically shown loose and installed by the creator. The paired files reproduce the cataloged left/right covers in black, crimson, silver gray, light silver gray, ultramarine and parchment variants; exact color must be selected or finished to match the vehicle. Installation uses expanding rivet 61131382239, but that separate fastener is not assigned as an OEM number for the printed covers.

Sedan/Touring Rear-Seat ISOFIX Cover
Since I lost two of my backseats isofix covers, I redraw them. Maybe someone else need them as well. I printed them with a 0,2mm nozzle, fuzzy skin at the frontside (strenght 0,04mm / distance 0,1mm), and forced support for the first layers…. The creator measured lost F10/F11 rear-seat covers and provides physical comparisons with the original. This is a cosmetic access cover only; confirm the ISOFIX anchorage remains fully accessible and unmodified. Verify dimensions against the original component and confirm full operation before regular use.

Electric-Seat Control Button
I made this part to hook on the little white knob to move the seat. I printed it with the arrows showing on top. 0.5mm extruder, 1h print time. supports on. Verify dimensions against the original part and confirm full operation before regular use.

Armrest Telephone-Delete Inlay Set
You probably do not use your E39 bluetooth phone anymore. Don't waste this space in your car and print my inlay to make this area useful for you. There are different versions available, I hope you will be able to chose the most fit for you;) I personally use the one with the grooves for phones. Verify dimensions against the original part and confirm full operation before regular use.

Gran Turismo Under-Seat Subwoofer Depth Adapter
4.5 mm depth adapter for installing a BLAM BM200W 200 mm subwoofer in the original HiFi enclosure of a BMW F34 3 Series Gran Turismo. Use cabin-rated material, isolate wiring and connectors, and verify secure fit and unobstructed speaker operation.

E92 Seat-Belt Presenter Hook
Seat belt hook attachment for BMW E92. Simply attach with a high quality double sided tape. Confirm normal seat, belt and presenter movement and keep the printed part outside the restraint load path.

Magnetic Rear-Seat ISOFIX Cover
Isofix cover for BMW E46 I was missing one of the isofix covers so I modeled and printed this one. It's not a perfect copy since I added a bit of thickness in some parts to make it stronger. You can see in one of the images the differences between the original and the 3d printed part. For this one the ABS filament is required since the PETG & PLA are not rigid enough. Added a magnetic version, magnet can be glued in place, 20 x 10 x 3 mm magnet size. This alleviates the need to print the part in ABS for strength. Print Settings Printer: TwoTrees Bluer Rafts: Doesn't Matter Supports: Yes Resolution: 0.2 Filament: Generic ABS Black Notes: Category: Automotive Confirm seat movement, belt access and occupant clearance before use.

Rear Seat-Back Panel Repair Clip
