This is was designed to connect a Ultrasonic Sensor to a Servo Motor with a blade. Specifically a HC-SR04 Ultrasonic Sensor and SG90 Servo Motor.
The original connecter broke so I designed a stronger one.
The tank and electronics is from this kit.
If you noticed the one of the top corners is missing a screw. That's because I lost it.
The author marked this model as their own original creation.
