Gone are the days when you have to choose a boring black square-edged enclosure for your device - now there are hundreds of choices, some with lovely smooth edges and even rubber hand grips. Go to somewhere like Digikey
in the US or Rapid
in Europe, and choose a box that is the right size and look for your project. Ideally, get one with a recessed area on the front panel for an overlay - in this image, you can see that each of these has a front panel area that is recessed by a fraction of an inch.
