Kid Trax Charger Police Car Gears

thingiverse

One of the gears in my sons police car stripped out, so I thought why not print some new ones to see if I could make it work. Hopefully this will help someone out. Enjoy. ***Update***4-30-2021- This is the second iteration of this project, the straight cut gears worked ok but were noisy and just did not mesh perfectly. On this attempt I went with a helical gear cut for all but the first stage on the bottom because I can not change the drive gear on the motor right now. These are confirmed to work in the gearbox, unfortunately after about an hours run time they stripped out due to the weakness of the PLA. I would like to try to print some in PETG as that is the only stronger material that my printer can print in.
