This is the emblem from the newest Man of Steel movie. It has pegs on the back to allow for attachment to cell phone cases or other items with a thin exterior. Just drill holes into the phone case or battery panel and then melt the tips of the pegs into the inside of the case.
Thanks to Shapeways user @dcherry88 for suggesting the pegs. This emblem is also available without pegs in a single or double-sided version. It is also for sale as a pendant and a ring on the Dimensionals shop.
