Rescale for Legion and some tiny edits of TheHivesMinds' wonderful AT-AT model kit. All the leg joints are articulated so it's posable yet the fit tight enough to let the walker easily stand on its own. Model is 489mm (19.2") tall; took roughly a week and a half to print at .32mm layers.
I'd like to take a second whirl at strengthening some of the belly attachments (at this size they're supporting quite a bit of weight) and may update the file down the road, but it's nothing a bit of hot glue wasn't able to easily remedy. I'd also recommend some more infill than I went with for the back sections (20% scaling down 5 times, so basically nothing) as those are a bit flimsier than I'd like.
Will update the images once it's painted!
