Star Wars Droid Build

This is a down and dirty Instructable to really let this community know about a fun project that I discovered some other Star Wars Junkies were building. I have a few SCI FI items in my movie room and once I saw this, I had to make this.
This is the summation of two resources and me doing the work. There is a guy in the UK who details a number of Droids in CAD / STL files and sells the files on Etsy (see link below). And another gentleman designed the arduino circuit that detects motion and plays sounds when motion is detected in front of the droid.
I had to modify the original droid 3D files to fit it up for the arduino circuit.
Where to go for the initial information starts with crediting…
