Yes, it's a derivative, which is attributed to the last author: http://www.thingiverse.com/thing:24675. There are also some up under my name, though they are all sold by carrythewhat: http://www.amazon.com/s/ref=bl_sr_3d-printing?ie=UTF8&field-brandtextbin=Emmett+Lalish&srs=8323871011. He's been selling my designs on Etsy for quite awhile and gives me 10% without my asking. We talked about the Amazon store before he put it up because he wasn't totally happy with the attribution (apparently links aren't allowed). It's experimental, but I appreciate that it's up under the designer's name (though I think people probably think I'm the one selling them). Anyway, yes, I'm on board.
