This time, I’m going to talk about a more personal and subtle aspect of SNOT: how to avoid grooves and gaps. And (perhaps a little bit ironic) I will also talk about LEGO Braille Bricks and how they can be used to achieve smooth SNOT surfaces—despite being purposely designed to be able to be recognized by touch.

You are most likely to have seen these on tiles and other elements where it would be hard to separate the pieces.
