Diamond Lattice - 3D Printed by sergeyalekseev.com

I 3D printed this to give as a gift on the Ruby conference. It turned out really well. As Ruby is my favorite programming language I like this design so much!! :) Don't know a lot of details about the print settings because used 3D Hubs. The only problem of this print - it's not smooth near the top. You can see it on the images. But I believe I can polish the ruby easily when I have time and inspiration for post processing my print.
