This is replacement gear shift knob. I include the OpenSCAD model so that you can adapt it to your particluar car. It is suitable for a 5 speed gearbox but can be adapted to another number, or remove one. There are two versions, one with a flat top that can be printed upside down for better resolution on the tet, and another one with a domed top that must be printed right side up, but where the text ends up a bit worse looking.
