1 Assembling the case.
- Put together part of the case as shown below.

- You are going to need to start with the parts below. Please note, the top and the bottom are not the same and there is a specific way around they go.
- Now add glue to the following edges.
- Start with a corner, make sure you use masking tape to hold it together.
- Now add the motor shelf, ensure the motor is facing the top side.
- Now you will need to glue the base in place. Collect the parts and put the glue on the edges.
- Start by placing the small top edge in place.
- Now glue the bottom front in place. Don't forget to use masking tape to hold it together.
- You will now need to collect the nuts for the switch and the Potentiometer.
- Start by placing the switch through the hole and adding the nut to the other side.
- Check that you have this on the correct side - note the smaller cut outs on the sides.
- Now you can add the Potentiometer.
- This can now be glues in place - the battery snap feeds through the hole at the back of the project.
- Place glue on the edges.
- The motor now needs to be cable/zip tied in place.
- Remember, the rough side faces inwards.
- The motor terminals need to face up.
- Once tied in place, the excess cable/zip tie can be cut using a side cutter.
