I do custom 3D models on request. and can also produce 3D files for fabrication in both traditional machining formats (IGES, SAT, 3DM) as well as (STL) stereolithography. ("3D Printing") So, if you have a project in mind, read my FAQ page here, then email me your proposal. Once I know the details, I can calculate a price for you pretty quickly. I also offer tutorials for 3D modelers, which you'll find on my Products page.
