This amazingly detailed DIY model starts as a 4" square steel sheet and finishes as an amazing 3D model. Just use the easy to follow instructions to pop out the pieces, and bend the table, then connect them at the attachment points. Most Metal Earth models take less than an hour to assemble, and on average measure about three inches long when completed. Each model averages 8-12 pieces. All can be assembled without any glue, although tweezers or needle nose pliers to bend the tabs will save you from sore fingers.
