Opel Ascona C Door Lock Cylinder Lever – OEM GM 90053650 | STL 3D Print

Über dieses Modell

A precise 3D-printable replacement door lock cylinder lever / actuator designed for the Opel Ascona C and corresponding to GM / Opel part number 90053650. This small component is fitted to the rear of the door lock cylinder and transfers the movement of the key to the internal door locking mechanism. After decades of use, the original plastic lever can become brittle, worn, cracked or completely broken. The lock cylinder itself may still work perfectly, yet one tiny failed piece can make the entire door lock useless. Naturally, forty years of automotive engineering can be defeated by several grams of plastic. This STL provides a practical replacement without requiring replacement of the complete lock cylinder or door lock assembly.
