Please note, eXtrudy does NOT create 3d reconstructions from multiple photos - use other software like "123D catch" for that.
eXtrudy helps users to create simple, printable 3D objects like jewellery, coins, medals, keyrings, pendants etc. from photos or drawings. Unlike the common 2D to 3D web applications it provides individual shapes, two sided objects, multiple decoration elements (engravings), hooks, volume calculation, .obj and .stl file export and a lot more. For simple tasks eXtrudy is much faster than complex modeling software. It is free, easy to use and you don't need any knowledge about 3d modeling. All results could be uploaded to your 3d printing service without further corrections/modifications. Or you could create them on your own 3d printer. Several tutorials are available on youtube.
