Basic gear system For Motors

Basic gear system designed for a basic (somewhat) high torque motor. Originally printed for a driveshaft of 2.5 mm by 3 mm, but by my estimation it is more suited for a gear with a 2.3 mm by a 2.7 mm driveshaft. I have not verified this functionality. If compatibility is desired with a 2.5 mm by 3 mm driveshaft than you can modify the smallest gear.
