I needed a Bezel for my ADX5, to keep it from LCD sliding off.  Needed something deep to make it hit the back enclosure  So I used OpenSCAD and its parameters, to setup my Bezel.  Though I would share it, since its parameterized  

There is an option to add a name section so you can name your bezel or printers.  You can also add small clips to lock it in place.

The parameters:

• Inside Depth (mm) - depth from front to make.  The clip if added will add to the depth
• Inside Width (mm) - how wide is the bezel
• Inside Height (mm) - how high is the bezel
• corner radius (mm) - how much to round the corners, to tight and it wont fit
• wall thickness (mm)  - how thick are the walls.
• lip width (mm) - how wide to make the overhang
• clip sides - if you want retention clips, none, 4 sides, top/bottom,. left/right
• width of clips (mm) - how wide to make the clips
• depth of clips (mm)  - how deep to make them, note to deep and it won't fit.
• name plate width (mm) - how wide to make name plate (width ≤ 0 no plate)
• name plate height (mm) - how high to make name plate (height ≤ 0 no plate)
• name plate radius (mm) - how much to curve the edges
• name plate offset (mm) - how far back to set name plate, most likely will require supports.

Note: if you use the name plate, add the name in the slicer, then flip over and print face down.

Note: the included X1C bezel was an example, it is off by 1mm in both directions, and is a little loose.
