Thrust Gear-Gear

This is a gear..with gears. There are 2 files: one has the gear teeth and one doesnt. They both have.2 tolerance in the internal gears. Planning on using it as wheels on a truck. I used customizer on emmet's thrust gear with: diameter 51.7, thickness 15, and tolerance .2. All other settings default. I found on my afinia .15 tolerance is a bit too tight.
