Here is a description from our site so you know the parts you'd need if you'd like to make one

The Echo Box is a complete kit. Fun for learning to program and play with an Arduino UNO R3. It comes fully assembled and works as a measurement tool. You can write a variety of sketches using the Ultrasonic sensor as well as program the LCD and all the buttons.

It includes:

1. Arduino UNO R3

2. HC-SR04 Ultrasonic sensor, with extension wires.

3. LCD Shield Kit w/ 16x2 Character Display for Arduino Uno R3, with extension wires and pin mounts. We get ours from Adafruit.

4. (2) 9 Volt batteries wired in parallel, with the Arduino Power plug adapter. This is the Power Pack for the Echo Box.

6. A pre loaded basic Distance sensing sketch and the downloadable source code.

In MakerWare, I modify the "Medium" settings:

Quality: Layer Height = 0.18

Infill: 15%

Shells: 2

For the battery base box, Arduino + Sensor Mount base, and top cover.

All other defaults are the same.

Building the Echo Box.

Print all the parts..

Wiring up the Echo Box is pretty easy. The Arduino just sits in the base mount. The HC-SR04 just mounts in the end. I solider on some short solid jumper wires to the Ultrasonic sensor, pins and plug them in.

Mount the LCD Shield. When we build these we use the extra long stacking headers. Then we plug in the Ultrasonic sensor in to the pins that are not used.

Hopefully that explained it all. Some of the pictures above also show the assembly. If you have any questions or suggestions please feel free to comment.
