Hi, the way to go with 3dprinting is with digital downloads. I set up the 3dfilemarket.com after cubify took down their open marketplace as I had over 80 designs on cubify that had a few hundred paid downloads. When they closed their marketplace I had no where to host my designs so I decided to set up my own website and people are downloading. Check out the accessories section of the site and you will see some nice iphone cases with excellent finishes if printed on a good printer. I have a solidoodle 2 printer and with a heated metal print bed with kapton tape. This gives an amazing surface finish.......
