Quick question for anyone who knows 3D printing – Which 3D printing company allows a 3D printing newbie to submit an STL file, and the company prepares/modifies the file as needed for 3D printing output? Ideally, a non-techie has the file, they send it to a company with "Here's my file," and shortly thereafter a 3D model lands on the user's doorstep. [Shapeways]() seems great, and they do flag issues, but they don't seem to change the file on behalf of the user. Any ideas?
