Thanks for the link. Yeah, I think the best I have found so far (and maybe it's just due to the qulaity of models on their site), but http://verold.com/ is pretty good.
The other issue I'm having is that I would kind of like to retain control of the model by hosting it myself. I already purchased "canvasio3D"- the WebGL-3D plugin for WordPress from virtuellwerk.d It works alright, but I'm having issues displaying .Objs. Right now it will only show .Stls. Weird.
