I printed one of these for my wife for Valentines Day. It turned out great. Some higher resolution pics are on my 3D printing page.
Please note that I didn’t design this, I found it online at: http://www.thingiverse.com/thing:408189, Louise Driggers is an amazing artist. Lots of precision fit parts and highly detailed models. My favorite part is the hidden/secret locking mechanism. Genius!
