Here is a Clone Sniper Helmet that I have unfolded and made available for you. It is game accurate to Battlefront 2. It is made with Pepakura 3, so if you haven't upgraded yet, you should to be able to view the file. I have scaled the model to the default size of 30 centimetres. I have not yet built the model myself, so I don't know if it will be too small/too big. This model is fairly chunky, so if you were going to fully build this thing with resin and fibreglass and such, a lot of bondo and sanding would be required. If you do build this model, I would be very thankful if you could post a picture or two. Thanks.
Here is the download link, I hope you enjoy.
