Hello, I'm Shadowjams. I wanted to let you know that I undid one of your recent contributions, such as the one you made to 3D printing, because it didn’t appear constructive to me. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks, Shadowjams (talk) 03:17, 4 August 2012 (UTC)
