For my work at Sketchfab, I've been playing with 3D scanners and photogrammetry software - tools that will reconstruct a 3D model from a series of photos. My favourite and free (as in beer) solution so far is Autodesk Recap360, and I've written a tutorial outlining all the steps to convert your photographs into a 3-dimensional model, clean them up to Blender and finally present them on Sketchfab. With a little practice, it shouldn't take you more than 30 minutes. (The model is downloadable, in case you're interested ;-)
