Welcome! Here are instructions to create gearbox that can easily be set to motorised or manual. It's hard to explain so here's a video:

The Base

Yeah, everything else goes on here.

This section is the motor.

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.

Moving Gear

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

The Manual Gear

If the motor jams, switch to this.

The "output" Gear

The rod is what to connect the turning part to. It could be any size.

How to Use (you're Done Anyway)

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