These components were created to mount a motor to the ball screw linear actuator (see below for links). There is both a NEAM 14 and 17 compatible motor mounts along with a shaft coupler that will allow you to bolt the motor shaft to the center of a MakeRig compatible gear (also linked below).

See this make for an idea of how the components all work together: https://www.printables.com/model/350128-ball-screw-linear-actuator/comments/546072
