Scrab (Scorpion Crab) Walker
This is a MOC created with the LEGO Star Wars AT-RT set 75002. It has a few extra pieces not included in the set, but they're pretty common bricks. It is relatively fragile, but stands without any need for support. Redesign and modify, give credits. Extra pieces from 75000 Clone Troopers vs Droidekas, and one white 4 x 2 plate from 9493 X-wing.
