A more printable version of the R2D2 thing by InnovationByLayers. While their model is commendable in its attention to detail, it was entirely useless as a printable model. I have taken the STL's into Blender and made considerable revisions both to make it manifold and printable without support. I tried my best to keep to the spirit of the design while fixing the overhangs and recesses that kept it from being something one could print on a 3D printer.
