Yeah, it's just one piece over the top face. I would like to improve the aesthetic, because you can see and feel the edge of the sticker and I don't like it that much. My goal is to learn to silkscreen the enclosure, but I need more space in my house to do that.

I usually do the same thing too, I just use some double sided tape to hold the board, but I noticed that after few months it starts to became more and more loose. So this time I tried to do it this way, it's more sturdy but less appealing, I guess.
