TMNT sewer cover w/ logo

Made this for a friend who wanted to attach it to a tattoo machine frame, here: http://www.thingiverse.com/thing:1287326 . The idea was to have the logo attached to a sewer cover. I could not find one here, so I took this coaster: http://www.thingiverse.com/thing:694011 And resized and attached this logo: https://3dwarehouse.sketchup.com/model/52550a04a3c1d6139a3cf89da53d9c30/tmnt to it.
