do you imagine any factory will produce a custom made enclosure for one buyer with one example?
Here is something you can do making your enclosure look professionally made.
Get yourself a fretsaw with metal cutting blades.
Use your PCB layout to draw (copy) the exact contours of the cut-out.
Drill four holes at each corner with a diameter not larger than the blade.
Use isapropanol alcohol (spirit) richly for a clean cut-out.
Depending on a steady movement of the saw blade and even alcohol feeding (using a brush) the cut will be clean and not require filing or any other treatment.
hi,
You can buy a range of LCD bezel's
I would suggest a APS [plastic] IP65 or IP68 water proof box, they come in various sizes and they are not very expensive [ easy to drill and cut] lcd bezel - Google Search
