Laser Cut Files in the Supplies
Supplies section from Tinkercad as an SVG le.
2. Upload les to your favorite vector software. TCPL uses Inkscape. Prepare the les based on the
requirements of the laser you are using.
3. Laser cut the parts on a 12x12 1/8 inch plywood board.
4. Once the parts are cut out hot-glue matching wheel pairs together.
5. Stretch a rubber band over each wheel.
6. Apply and spread hot glue along the rectangles at the back of the chassis. See the second photo for an
example. This will keep the motors from sliding around and make then adjustable.
7. Download the 3D Print File
3D Print File in the Supplies
Supplies section from Tinkercad as an STL le.
8. Import the STL in your favorite slicer. Make sure to set the in ll to 15% and supports on.
9. Once the print is complete clean o the supports.

Note:
Note: If you are unable to access a laser you can print the SVG les out and use a scroll or coping saw and drill to cut out
the parts.

Step 2: Wire Motors
At TCPL we have developed a way to attach wires to the DC motors without the need for solder. This was done to
streamline repairs during races. If you are comfortable using solder attach the wires that way.
1. Take two M-to-M wires and cut them in half and strip each end without a pin.
2. Twist the wire brush into a tight wrap and slide it into the DC motor input. See the second picture for an
example.
3. Once the brush is secure in the DC motor input lightly pull it down the side of the motor bell and glue it in
place. Be careful not to get glue on the motor input of the shaft. See the third picture for an example.
4. Repeat the process for the other DC motor input so there are two wires attached to it.
5. Tightly wrap the electrical tape around the bell of the motor to cover the exposed wire brushes.
6. Repeat this process for the second motor.
7. Once both motors are ready slide a motor clip on each. You will see a round circle protruding from one
side of the motor, the open side of the clip goes around this. See the 9th picture for an example.
8. Slide a clip onto each motor.
