3D model and print of the enclosure for the device is ready. Small changes should be made but overall everything fits together nicely. One catch, though, is that ABS material used for print is quite translucent and backlight from LCD screen illuminates through the material. This could be fixed by using additional light blocking insert or making front part thicker and having less translucent material.
Model was designed using FreeCAD and consists of two parts bolted together.
