Users of Raspberry Pi model 3B+ (RPI3-MODBP) may be familiar with the 7 inch IPS Touch Screen LCD Display Monitor HD 800x480 with HDMI by TeNizo, part number B07N1MP4NH, rev 2.0, which can be found on Amazon.
What seems to be difficult to find is a bezel for it. A "bezel" is a mount for the display, looking like a frame from the front, but having means to attach the display board to it, as well as means to attach it to a sheet-metal panel. So I offered to management here that I could design and print a bezel, and this is the result.
For attachment to a sheet metal panel, I have 4 pairs of slots for these little metal brackets with screws that push against the sheet metal. The brackets came with a bezel we had bought for a different display. I'm sure they must be available separately, but I haven't bothered finding them. In the next few days, I will either find them and put a link to where you can get them, or else I will design a printable bracket to fit those slots.
I will upload gcode for PETG tomorrow (I have the file in my other computer), and for PLA maybe next week, as right now I'm out of PLA so I could not test it.
UPDATE: Added gcode for PETG, but it prints a bit rough. I haven't completed my PETG learning curve purgatory yet.
In addition to slicer generated supports, those L-shaped things at the corners are manual artifacts for holding the corners down, otherwise they tend to warp up. Just cut them off after printing.
