I meticulously modeled this studio scale ESB AT-ST. It is the same size as the filming puppet built by ILM. It is hyper detailed to every last rivet. It can be assembled to be fully poseable over a dozen points of articulation. Modeling experience will be necessary to achieve such articulation (drilling holes, installing hex cap nuts and bolts, etc..) The file set includes decal artwork (PDF), STL .rar folders for each body section, illustrations, etc.. I don't have any printed instructions to share but the build is very similair to my ROTJ AT-ST and I do have video instructions for that project linked here.
