I have a Barbie Lamborghini with the #3 gearbox and a 3D printer. I'm going to try printing a new 8 tooth pinon based on this design:

I see in the definitive gearbox thread that it is not a 32 pitch, but have not been able to find a post that does give a pitch. Any suggestions on starting values would be greatly appreciated. I'll decrease the teeth to 8, put a caliper on the old motor and pinion to get the diameters and thickness, and put a flat spot in the center to match the motor flat spot.

I'm not sure the gear will hold up well, but they should be easy to print and I could try nylon instead of PLA, or turn it into a mold and try some other materials. Thank you. Paul...
