Sorry didn't know it was an edit. Makerloom allows prospective buyers to look at a preview of the 3d model that they may want to download. They can look at it right in the browser (thanks to webgl). Also not all models are for sale, we actually encourage our makers/sellers to list some of their models for free. I'd like to add more features but I need more users so I can know the features that would be useful to them.
