Assembly:
- The wheel_lower part fits with the wheel_upper part with 3 M3x16 screws.
- Align the three screw-holes precisely as sometimes the holes might align but the alignment of the lower and upper bodies might be off by 120 or 240 degrees.
- The wheel_cap ( this part was not tested by me as I only had M3x20 screws available) can be used in place of nuts to hold the body parts together.
- One M3x16 screw goes through the center of the wheel to the servo.
