Amphibious walking ship from the game Supreme commander.
Pulled the original model from the game then modeled onto it the textures (I only eyeballed them, to be 100% accurate, more work would be required and printing at a smaller layer height). Made changes to the original model to fix intersecting geometry, so that the legs can fold into the hull., etc.
The legs have M3x20 screws for articulation. The pontoons move on a four bar mechanism. Both turrets rotate, the AA turret also elevates.Oh, and it also floats. The transformation consists of folding of the legs, raising of the pontoons and retracting of the rear of the ship -video:
