Seat-Adjustment Repair Handle

Bolt-on replacement handle for broken manual seat-adjustment levers. The creator explicitly designed and photographed it for both 116-series and 123-series cars, states that it can be used at all four handle positions, and notes that side height adjusters accept one screw while the front adjusters use two. The demonstrated part was printed in PETG, sanded and buffed, then fastened through the surviving metal lever with screws and nuts. Remove only the remains of the failed grip, preserve the original lever, deburr all holes, use secure low-profile hardware, and confirm full adjustment and locking travel before driving.
