Step 1: The Base

The gear from the motor could mesh with another... if it's set to.

Step 4: A Bit of Support

It's easier if this is just an extra step. If not the next step is too long.

The added pieces in this picture are: 1 green rod, 1 white rod, 1 blue rod, and 1 yellow connector.

Step 5: Moving Gear

This gear shifts forwards and backwards to mesh with either the motor's gear or the manual gear.

Step 6: Adding the Shifting Gear

This clips straight onto the motor.

Step 7: The Manual Gear

If the motor jams, switch to this.

With the motor facing towards you, if the trigger is left, turning is manual, if the trigger is right, then the turning is motorised.
