This design caters to diverse PM motors, including large and small CIMs as well as 775-type motors. It features three sets of 20DP gears on 2.1" centers for versatile use. The illustration shows 0.5" hex ID bearings. VexPro offers an extensive range of compatible gears (https://www.vexrobotics.com/vexpro/motion/vexpro-gears/1-2-hex-bore.html). On November 2, 2018, the design was updated to include fasteners and lengthened mounting tabs due to a "design exercise" being built, necessitating these modifications.
