Gears 17t to 39t. You can make whatever ratio you want.
Consider to follow if you like what I do.
Just ask if you have an idea to a brick piece you want to be made.
As the title says. Make your own version of the gears.
This pack contains all the gears from 17t to 39t.
I have only tested a few, but they're all made with the same specs with the gear generator so they should work fine.
