Metal Earth Ferris Wheel model kit is an amazingly detailed etched model that is fun and satisfying to assemble. It starts as 2 4-inch square steel sheets and finishes as a 2.93″ x 3.55″ x 1.29″ 3D model. Simply use the easy-to-follow instructions included with the sheet to pop out the pieces, bend the tabs, and connect them at the attachment points. No glue nor solder required.
