This is to replace a the instrument panel brightness control knob in a 1989 Toyota Camry it can be found on the left of where the steering wheel attaches to the rest of the car, I only took into consideration the shape of the peg it had to fit onto. I did not try to make this an accurate replica of the knob that originally came with the vehicle.

I used Tinkercad because I no longer have access to CATIA on the school computers(I graduated). This part is really simple, just a cylinder and a square hole so CATIA capabilities were not required.
