Consider to follow if you like what I do.
Just ask if you have an idea to a lego piece you want to be made.
As the title says. Make your own copy of the Lego gears.
This pack contains all the gears Lego did make. But its easier to make them at home.
I have only tested a few, but they're all made with the same specs with the gear generator so they should work fine.
layer height: 0.1, initial can be 0.2, but then you'll get a small elephant foot
Perimeters: 12 (just to be sure it only using lines, no infill)
