8 Series

Adapter for fitting a Dayton Audio RS75-4 midrange driver to the front-door and rear-deck speaker enclosures of BMW E31 840 and 850 models. The creator supplies STL, 3MF and Fusion 360 source geometry and physically demonstrates the adapter loose and fitted in the factory enclosures; mounting holes require drilling after printing. This adapts aftermarket hardware rather than reproducing a BMW component, so no speaker-box parent number is assigned. Verify cone, grille, wiring and fastener clearance before reassembly.

Fits 8 Series · E31

Right-hand-drive console cover for fitting an E60 M5 SMG selector in a BMW E31 8 Series, physically shown installed by the creator and printed in PETG at 50 percent infill. This is custom retrofit geometry rather than an original E31 service component, so no parent console, selector or trim number is assigned. It applies only to RHD cars with this specific conversion; confirm selector travel, wiring clearance and secure console retention before driving.

Fits 8 Series · E31

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

Four-print set of replacement fulcrum sleeves for the BMW E31 pop-up headlamp bucket, physically shown loose and installed at the upper bucket attachment by the creator after replacing warped original inserts. BMW catalogs identify the separately serviced joint sleeve as 63121392066, position 13 in the headlamp component diagram and six per vehicle. Print in heat-resistant material, replace all damaged sleeves, then verify bucket retention and have headlamp aim checked before night driving.

Fits 8 Series · E31

Replacement plastic pivot base for a BMW E31 sun visor, supplied for the left/right location and physically shown both loose and installed by the creator on an 850i. The original metal visor shaft is reused and its diameter can vary; drill the centre only as needed for a careful fit. BMW services the surrounding colour-specific electrical-contact bracket as a complete assembly, so those parent/contact-bracket numbers are not assigned to this printed repair body. Match anthracite, silver-grey, parchment or Individual trim and verify mirror-light contact operation before use.

Fits 8 Series · E31

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.

Dimensioned replacement glovebox damper pin for BMW E21, E28, E30, E31, E34, E38, E39, E46 and E60/E61. The creator identifies BMW pin 51161828956 and shows the physical result installed. Verify damper eye and panel thickness before fitting.
