The files for this model have been removed from this page, from now on the files can downloaded for free from www.MyMiniFactory.com. This page will be left for legacy purposes and I will still answer questions if posted.
Sorry for any inconvenience.
After seeing the first trailer for episode 7 and thought this droid looked awesome. The model is 1:1 scale with the head being roughly being the same diameter as R2's.
