Romeo Blue (Pacfic Rim)
One of the less seen Jaegers in Pacific Rim, Romeo Blue was the first USA-sponsored/built Jaeger (not counting the prototype Brawler Yukon), and the second Jaeger to score a Kaiju kill.
Original model was available for free on another site, scaled in blender to approximately 255mm tall (according to size chart Romeo Blue should be 255 feet tall for reference) and exported to STL for 3D printing.
