Etsy seller Niquegeek made these 3D printed stainless steel dice that resemble the beloved weighted companion cubes from the game Portal. They're hollow, and retail for $29.
This unique die (singular dice) is made layer by layer in a 3D printer and then fired to fuse the metal particles into solid steel.
It is available in a numbered version, a version with just hearts (similar to the pendant I also make) and now a numbered version with a heart for the 1! It makes 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.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
