This is a set of gears intended for use to replace the broken gears in a 300ZX blend door actuator. This includes all the gears in the geartrain except the worm on the motor, which I could not extract to model.
Shown in the pictures is a small puller I had to make to remove the actuator arm intact.
Given the forces this is subject to, I would not recommend printing these in anything short of ABS or Nylon, at 100% infill. I printed in Taulman 910.
