HC-SR04 box

The box is designed to fit the HC-SR04 ultrasound ranging sensor. It features a cover to close off the sensor and a small rectangular hole to allow for the 4 pins to be connected. The two holes at the bottom allow for the sensor's probes to come out neatly. Some small adjustments might be required to fit trough the holes, depending on your printer. The cover can be sealed using two small self-tapping screws.
