I don’t know about you, but when I build a project, I like it to look right as well as work right. Most holes you drill can be done neatly…and / or covered by a washer or knob…but there’s a problem with 16×2 LCD display bezels; there are thousands of displays to choose from but no bezels.
I’m relatively proficient with metalworking tools, but it’s still almost impossible to get a professional finish with hand tools alone. Chances are you will end up with something looking like the picture on the right…or much worse. By the way, the work shown in the picture is not mine!
I managed to source some bezels in the USA but the manufacturer wasn’t keen on sending samples…or being very helpful at all if I’m honest. There is now a UK based supplier of purpose designed 16×2 LCD display bezels…the link to the bezel is here. You still have to cut a neat hole…but the bezel will cover all your file marks leaving a professional finish.
I only wish there were more styles on the market to choose from…but I suppose most 16×2 displays go into moulded or machined enclosures…where the cut outs are made by machine 🙁
Update: Just come across another one here.
