Topic: new 3d file search engine YOBI
spent hours last night looking through it.
seems it locates free downloadable 3d printable file types web wide then links to the sites. some require registering b4 hand and not all file types available nor pre-tested for print-ability. the main down side is this site loads 100s of thumbnails with search results much more than when 1st going onto youtube. making it 1st very slow due to over working memory like way over 1gb. then locking up browser making you have to re-start browser to clear plus clear cache often.
otherwise its really cool about finding files for hard to locate models. I found a dozen or so that I have been searching all main repositorys for years for. also bookmark sites linked to as they are other small repositorys some only have other file types than stl but many RH will open then export stl but check exported stl in netfab b4 deleting zip of original as some need further fixing to make printable. some even loose parts of model during export some how.
also its a bit difficult finding where to click to get downloads. so have fun lol.
