This nano scale Lego AT-ST is created by NS Brick Designs. A neat thing about this little mech is that it is made out of very common parts, usually the kind you get two or three extras of in a set. You can find lightsaber hilts, the small Lego guns, and even a Minifigures hand in this build. The chicken walker style design of the AT-ST is surprisingly sturdy at this scale, and is not as fragile as it looks. The scene is finished off with a SNOT style rock base, and a little Lego antenna (which represents a Stormtrooper).
NS Brick Designs made a quick set of instructions to show how to build your own nano AT-ST. The whole thing uses just 18 common Lego pieces. The most confusing part is in step two. There are three 1×1 clips and a 1×1 brick. The two on the bottom are facing away from each other and connected by the clip on the top. This is a fun little build
