Based off of the infamous Weighted Companion Cube from Portal
This unique pendant is made layer by layer in a 3D printer and then fired to fuse the metal particles into solid steel. It also makes a great key-fob and is the perfect gift for the Portal fan in your life.
Each side of the cube measures 9/16" across and it is hollow so it's much lighter than it looks. Each pendant is unique and the finish may vary slightly from the images.
