R2D2 - This is the Droid You're Looking For

The survey for my next project has been closed. I'll have a video posted shortly detailing the winner and my plans to create it! This is a 3D Printed R2D2 powered with an Arduino. I started out sketching things on note cards, after that I looked up a bunch of reference images on Google to work out the dimensions, then I went to Tinkercad to start modeling it out. After that I printed the parts out using PLA on my Robo 3D Printer. The biggest prints are the body that took around 10 hours and the head that took about 6 hours to print. The rest of the parts took anywhere from 2-3 hours. The whole project totaled about 30 hours of printing time. I printed everything at 0.3mm layer height but the quality can be improved if you decrease that. After it printed I handed it off to my wife so she could paint it. She picked up some plastic spray primer to help the paint stick. Then she painted on the details with acrylic paints and a brush. Then she gave it a clear coat afterwards to avoid da
