GM Grand Prix Door Lock Knob

thingiverse

My 13-year-old son and I crafted this design as a replacement for a faulty knob, and this item claims to be discontinued from General Motors parts. It's specifically designed for a 2006 model, but we expect it to function well in numerous GM vehicles from around the same era. You'll need to handle threading yourself using a screw, but the results should be satisfactory.
