Modeled and printed this as a gift for one of my best friends who I met through Garrys Mod many years ago. 

I wasn't a fan of how the existing models on Printables and Thingiverse connected the letters together; this one has a slight draft/taper to the interior of the letters, so that they connect together at the back. From the front, this taper isn't very obvious, and looks fairly seamless.

The outer border of the model remains flat, so that the text can sit flat.
